Description

TECHNICAL FIELD

[0001] The present application relates to the field of computer shortcut keys, and relates to a method and device for realizing shortcut keys based on combination of a single specified function key and one or more character keys. BACKGROUND

[0002] As an important input device, a keyboard is an important component of computer products such as notebook computers, desktop computers and virtual machines. As convenient instructions provided by operating system and application program developers for users, shortcut keys can more conveniently and quickly operate the system and application program, and usually have rich functions and convenient characteristics.

[0003] Currently, computer products for individuals usually adopt the following methods: 1. a single modifier key + a single character, such as "Ctrl+C / Ctrl+V", and 2. multiple modifier keys + character keys, such as "Ctrl+Alt+A". (Note: modifier keys are different on different types of operating systems, such as Ctrl / Alt / Logo key / CapsLock on Windows and Linux operating systems, and command / control / option / capslock keys on Mac operating systems, which are similar to Windows / Linux functions.) Limited by the number of single character keys, when there are a large number of available shortcut keys in an application program, multiple modifier keys are usually required to participate in realizing the shortcut key instructions, and the complexity of the operation reduces the convenience of users using the shortcut keys, and similar characters in the shortcut keys increase the difficulty of users remembering the shortcut keys.

[0004] Therefore, in view of the above problems, the present application provides a method for realizing shortcut keys based on combination of a single specified function key and one or more character keys, which can realize specific shortcut functions by using a single specified function key and multiple character keys, increase the range of shortcut key combinations, reduce the difficulty of shortcut keys, and provide a user with a letter combination-based classification method to reduce the difficulty of remembering. SUMMARY

[0005] The present application provides a method for realizing shortcut keys based on combination of a single specified function key and one or more character keys, which can realize specific shortcut functions by using a single specified function key and multiple character keys, increase the range of shortcut key combinations, reduce the difficulty of shortcut keys, and provide a user with a letter combination-based classification method to reduce the difficulty of remembering.

[0006] In view of the above purposes, one aspect of an embodiment of the present application provides a method for realizing shortcut keys based on combination of a single specified function key and one or more character keys, including the following steps:

[0007] It should be noted that the specified function key is a preset or custom keyboard key, which can be divided into modifier keys and character keys. Modifier keys are different on different types of operating systems, such as Ctrl / Alt / Logo keys / CapsLock on Windows and Linux operating systems, and command / control / option / capslock keys on Mac operating systems, which are similar to Windows / Linux functions. Character keys are single keys in the main keyboard area that can achieve corresponding functions, including but not limited to: letter keys, symbol keys, number keys, direction keys, F1-F12 keys, etc. User key input events include key events and release events. In this article, a single specified function key refers to this matter.

[0008] A single specified function key is used to distinguish between text input mode and shortcut instruction mode. When the user presses and holds a single specified function key, the system enters shortcut instruction mode, intercepts key input and converts it into a shortcut instruction, and then sends the corresponding key value to the shortcut processing component in sequence. The system matches the shortcut instruction according to the continuous key input in the shortcut instruction mode.

[0009] When it is detected that the specified function key is pressed, it is in the shortcut instruction mode, and the intercepted key input event of the system will no longer be passed to the operating system, thereby temporarily shielding its original function. When the specified function key is not pressed, all other keys will perform their original functions except the specified function key.

[0010] When the shortcut processing component receives an instruction, event or message, it stores the instruction, event or message in the key instruction register, and then compares the instruction register and the corresponding shortcut key that has been set according to the shortcut key rule.

[0011] When the user is in the shortcut instruction mode, the shortcut key rule is: 1. For character keys, press them in sequence and any single character key does not need to be held down. The interval between keys is unlimited. 2. For shortcut instructions with non-specified other modifier keys and function keys, press the non-specified other modifier keys or function keys at the same time, and then press the character keys in sequence.

[0012] According to one embodiment of the present application, when the instruction register cannot be partially or completely matched with the preset shortcut instruction according to the shortcut key rule, it will cause all future keys to become invalid instructions. In this case, the instruction register is emptied and the instruction acceptance state is initialized, thereby preparing for new key input.

[0013] According to one embodiment of the present application, when the user is in the shortcut key instruction mode and a preset shortcut key instruction length is greater than or equal to 2, after the instruction register receives a new key event, partial instruction matching is achieved according to the shortcut key rule (for example, the shortcut key instruction is to press the letter "a" first and then press the letter "s", when the instruction is in the state of having pressed "a" and not having pressed the letter "s"), the instruction register state is maintained, and new key event input is continuously detected and received.

[0014] According to one embodiment of the present application, when the instruction register stored shortcut key instruction matches the preset shortcut key, the shortcut function is executed, the instruction register is emptied and the instruction acceptance state is initialized, so as to prepare for new key input.

[0015] According to one embodiment of the present application, when the instruction register is emptied, if the specified function key still maintains the continuous key pressing state, the shortcut key instruction mode continues to accept new shortcut instruction input.

[0016] According to one embodiment of the present application, when the user releases the specified function key, the shortcut key instruction mode is exited and the register is emptied, and the normal key input mode is restored, so as to prevent interference on the next instruction matching.

[0017] According to one embodiment of the present application, when the specified function key is a modifier key, the shortcut key instruction mode is entered by pressing and maintaining the function key, and the shortcut key instruction mode is exited by releasing the function key.

[0018] According to one embodiment of the present application, when the specified function key is a character key, after the function key is pressed and maintained, the system first saves the key value of the current key, when the shortcut key instruction mode is entered, if the user presses the shortcut key instruction related key, the saved key value is cleared, if the user does not press the shortcut key instruction related key in the shortcut key instruction mode, the shortcut key instruction mode is exited and the saved key value is sent to the system, the "key-release" action is completely simulated, and the original function of the key is ensured.

[0019] Another aspect of the embodiment of the present application further provides a device for implementing a shortcut key based on a single function key and a plurality of character keys, which uses the above method.

[0020] Another aspect of the embodiment of the present application further provides a computer device, which comprises a storage unit, at least one processing unit, and a computer program stored in the storage unit and executable on the processing unit, and the processing unit uses the above method when executing the program.

[0021] The application has the following beneficial technical effects: the method and program provided by the embodiment of the application based on single function key plus character key combination realize three main goals: (1) increase the number of shortcut key combinations: the application expands the combination possibility of shortcut keys by using letter combination, for example, using 2 letter keys to combine shortcut keys, (26+10+10) 2 = 2216 shortcut key combinations, using 3 letter keys to combine shortcut keys can realize (26+10+10) 3 = 97336, and the number can continue to double in the case of adding other modifier keys (2) simplify the shortcut key pressing method: reduce the inconvenience caused by pressing multiple modifier keys at the same time, and using single specified function key plus multiple character keys can reduce finger movement on the keyboard, thereby improving the efficiency of key pressing. (3) provide shortcut key classification options to reduce user memory burden: assuming that the number of characters in the character combination is n, then the first n-1 characters in the character combination can be used as the common part of the same type of shortcut key, and the last character is the corresponding specific shortcut key instruction (for example, QA and QS can be regarded as the same type of Q series shortcut key instruction, and similarly, AAS and AAD can be regarded as the same type of AA series shortcut key instruction).

[0028] To make the objectives, technical solutions, and advantages of the present invention more intuitive, the following detailed description of the present invention is provided in conjunction with specific embodiments and with reference to the accompanying drawings.

[0029] It should be noted that all expressions such as "first", "second" and "third" used in the embodiments of the present invention are for the purpose of distinguishing two entities or parameters with the same name but different names. It can be seen that "first", "second" and "third" are only for the convenience of expression and should not be construed as limiting the embodiments of the present invention. Subsequent embodiments will not explain this in detail.

[0030] To achieve the foregoing objectives, a first aspect of the present invention proposes a method based on a combination of a single function key and character keys. Figure 1 The diagram shown is a basic flowchart of the method based on a combination of a single function key and character keys provided by the present invention.

[0031] Step S01: When the user presses and holds the specified function key, the shortcut key instruction mode will be entered. At this time, the key events of character keys and other modifier keys will be intercepted and sent to the shortcut key processing component, and stored in the instruction register.

[0032] In step S02, under shortcut key instruction mode, the system will continue to detect the user's keyboard key events. When the user presses character keys in sequence (if other modifier keys are present, the corresponding modifier keys will be pressed simultaneously), after each character key is pressed and the key event is stored in the instruction register, the system will detect the matching with the preset shortcut key instruction.

[0033] Step S03: There are generally three matching scenarios between the instruction register and the preset shortcut key instruction: When the current shortcut instruction stored in the instruction register completely matches the preset shortcut function instruction, it is determined to be valid and the specified shortcut function is executed, and then the instruction register is cleared; when the current shortcut instruction stored in the instruction register partially matches the preset shortcut function instruction, the current function states are maintained, and the system continues to detect the user's next key input; when the current shortcut instruction stored in the instruction register cannot match the preset shortcut function instruction and there is no longer any possibility of matching with the preset instruction, the instruction register is cleared, and the process returns.

[0034] According to one embodiment, such as Figure 2As shown, the system will continuously detect user key input events after starting. After detecting user key input, the system first distinguishes whether the key event belongs to a specified function key. If it is a specified function key in a pressed and held state, the system will enter a shortcut key instruction mode and continue to detect subsequent user key inputs. If it is a non-specified function key (i.e. a character key or other modifier key), it is necessary to determine whether the current specified function key has been pressed (whether it is in the shortcut key instruction mode). If the specified function key is not in the pressed and held state, the corresponding key event will perform its original function.

[0035] According to one embodiment, as shown in Figure 2 If the specified function key is in the pressed and held state (i.e. in the shortcut key instruction mode), the system will intercept the key event so that it is no longer sent to the operating system for processing, and the key event will be sent to the shortcut key processing component. The shortcut key processing component includes an instruction register, a preset shortcut key instruction matching operation, and an execute shortcut key action function. When the shortcut key processing component receives a key event, it first sends the event to the instruction register for storage, and then matches it with the preset shortcut key instruction.

[0036] The role of the instruction register is to store the key state of the current shortcut key instruction. For example, the preset shortcut key rule is to press the characters 'a','s', and 'd' in that order, and the user has already performed the key actions of 'a' and's'. The register will save the key events of 'a' and's', and include the key sequence.

[0037] After the instruction register receives and stores the latest key event, the shortcut key processing component will match the key state currently stored in the instruction register with the preset shortcut key instruction according to the shortcut key rule, including the key sequence and the corresponding characters.

[0038] The shortcut key rule involves two types of keys: character keys and modifier keys, except for keys designated as special function keys. Among them, the rule for modifier keys is to press and hold them simultaneously, without paying attention to the key sequence; the rule for character keys is to press them in sequence, paying attention to the key sequence, and not requiring simultaneous pressing.

[0039] According to the shortcut key rule, when the shortcut key instruction stored in the instruction register is a part of a preset shortcut key instruction or a part of a certain type of shortcut key (e.g. a preset shortcut key rule is to press the characters 'a','s', and 'd' in that order, and the register saves the key events of 'a' and's' in that order), it is considered a partial match. At this time, the shortcut key processing component will retain the data in the register and continue to detect the next key event of the user.

[0040] According to the shortcut key rule, when the shortcut key instruction stored in the instruction register is completely matched with one of the preset shortcut keys (for example, a preset shortcut key rule is to press the 'a' and's' characters in sequence, and the register stores the key events of 'a' and's' in sequence), it is considered to be completely matched, and at this time, the shortcut key processing component will execute the corresponding shortcut function according to the shortcut key.

[0041] According to the shortcut key rule, when the shortcut key instruction stored in the instruction register loses the possibility of matching with the preset shortcut key (for example, a preset shortcut key rule is to press the 'a' and's' characters in sequence, and the register currently stores the key event of the character 'd', and there is no other shortcut key in the preset shortcut key whose first character is 'd'), it is considered to be a matching failure, and at this time, the shortcut key processing component will clear the instruction register and prepare to receive the next user's shortcut key instruction input.

[0042] The operations involved in the foregoing [0035-0041] are all in the shortcut key instruction mode.

[0043] When the user releases the specified function key, the shortcut key processing component will perform a clearing operation on the instruction register and exit the shortcut key instruction mode.

[0044] Figure 3 The difference between the specified function key being a modifier key or a character key will be further explained. According to user usage habits, the function key can be specified as a modifier key or other character key (including but not limited to letter key, symbol key, number key, direction key, etc.).

[0045] When the specified function key is a modifier key, it is pressed and held to enter the shortcut key instruction mode, and released to exit the shortcut key instruction mode.

[0046] When the function key is a character key, in order to preserve its original function, the key value of the key is saved after being pressed. After entering the shortcut key instruction mode, if the user presses the shortcut key instruction related key, it indicates that the user performs a shortcut key operation, and the saved key value will be cleared. If the user does not press the shortcut key instruction related key in the shortcut key instruction mode, the system will be sent the saved key value when it is released, completely simulating the "press-release" action, and ensuring that the key functions as originally intended.

[0047] Figure 4 The extension of the present application will be further explained, which increases the number of shortcut key combinations: by using the combination of letters, the combination possibility of the shortcut key is expanded. Figure 4For example, using four keys (e.g., 400) and two-key combinations, this provides 4 x 4 = 16 shortcut key options (e.g., 410). If we consider 26 letter keys, 10 number keys, and 10 common symbol keys, using two-key combinations for shortcuts, the total number of shortcuts is (26 + 10 + 10). 2 = 2216 keyboard shortcut combinations, which can be achieved by using 3-letter key combinations (26+10+10). 3 = 97,336 keyboard shortcut combinations, and this number can be doubled when additional modifier keys are added.

[0048] according to Figure 4 As shown, this invention can provide users with the option to categorize shortcut keys, reducing the user's memory burden. Assuming that the number of characters in a character combination is n, then the first n-1 characters in the character combination can be used as the common part of the same type of shortcut key, and the last character is the corresponding specific shortcut key instruction (such as 411, UU, UI, UJ, UK can be regarded as U series same type of shortcut key instructions).

[0049] It should be particularly noted that the steps in each embodiment of the above-described method for implementing shortcut keys based on a combination of a single specified function key and character keys can be interchanged, replaced, added, or deleted. Therefore, these reasonable permutations and combinations of the method for implementing shortcut keys based on a combination of a single specified function key and character keys should also fall within the protection scope of this invention, and the protection scope of this invention should not be limited to the above-described embodiments.

[0050] Based on the above objectives, a second aspect of the present invention proposes a device for implementing shortcut keys based on a combination of a single designated function key and character keys.

[0051] As can be seen from the above embodiments, the device for implementing shortcut keys based on a combination of a single designated function key and character keys provided by the embodiments of the present invention can detect user key input events and process them accordingly. It can achieve specific shortcut functions by utilizing a combination of a single designated function key and multiple character keys, increasing the range of shortcut key combinations, reducing the difficulty of key presses, and providing users with a method of categorizing shortcut keys based on letter combinations, thus reducing the difficulty of memorization. This improves the convenience of user operation, enriches the functionality of the keyboard on the basis of existing hardware, and is simple to implement.
