Portable terminal

Abstract

The invention provides a portable terminal which can increase the function of text editing. This portable terminal is provided with a setting control part 26 which sets the contents of a character erasing operation, a display part 10 which displays a cursor on a display screen, a position deciding part 22 which decides the reference position of character erasure at the display position of the cursor and an erasure control part 24 which controls a character erasing operation based on the display position and reference position of the cursor according to the contents of the character erasing operation when a clear key is depressed. In addition, when the cursor is at the start character position of editing text or final character position, a cursor control part 28 controls the shift operation corresponding to cross key, so that the cursor performs the preset action, and the preset action of the cursor is set by the setting control part 26.

Description

technical field [0001] The present invention relates to the improvement of the text editing function of the portable terminal, and particularly relates to the improvement of the deletion control of the input characters and the improvement of the cursor movement control. Background technique [0002] Conventionally, portable terminals such as mobile phones have provided text editing functions such as writing email texts. In the case of text editing on such a portable terminal, if it is necessary to delete the input characters, the character deletion is performed with the clear key. [0003] As a technique for making such a character deletion operation more efficient, Japanese Patent Laid-Open No. 8-305687 describes that if a number at an arbitrary position in a number column is deleted, the position of the bit indication flag is automatically corrected to an appropriate position. composition. [0004] However, in the portable terminal of such prior art, there is only one cl...

Problems solved by technology

[0007] But, in the portable terminal of such prior art, although only by the cross key the movement of front and back pages is possible, but there is only using the cross key to make the cursor move from the beginning of the text to the end or from the end in a short time. Insufficient technology to start mobile operations

[0008] In addition, in the conventional technology, when the cursor is located at the start character position or the last character position, if the cursor is operated to move the cursor up, down, left, right, that is, in a direction where no characters are displayed, the cursor can only perform one action depending on the model. , not necessarily a composition that makes it easy for users to use
