Description

Description: TECHNICAL FIELD OF THE INVENTION This invention relates to improvements in systems.

[Technical background of the invention and its problems]

When editing a sentence, mistakes in editing instructions often occur. In such a case, there is an edit cancel function that cancels the content of the edit instruction.

Many of these undo functions were last operated
Only the contents of the editing instruction for the batch are canceled. For example, if you press the delete key 10 times for each character and delete the 10 characters immediately after the edit cancellation is instructed, the last 1
Only the delete character operation is invalid. The remaining 9 characters need to be input again, which is troublesome and is likely to cause another mistake during input.

For this reason, there is an improved text editing system so that, when an edit cancel operation is instructed 10 times, for example, the deleted 10 characters can be reproduced. However, in such a text editing system, all operation processes must be stored, a large-capacity storage unit is required, and if not installed on a high-speed computer, the user will not feel uncomfortable. It becomes difficult to respond in the range (2 seconds or less).

[Object of the Invention]

An object of the present invention is to provide a text editing system in which editing operations by an operator are simple.

Another object of the present invention is to provide a text editing system capable of canceling editing with a small number of operations.

[Outline of Invention]

According to the present invention, correction contents by the same edit key are stored until another edit key or cursor key is input, and when the edit cancel key is pressed, all corrections by the same edit key are invalidated. It is a text editing system.

〔The invention's effect〕

According to the present invention, since the user can invalidate all the series of operations with one touch, the burden on the user can be greatly reduced.

Therefore, the editing operation can be significantly simplified, and an appropriate sentence can be easily obtained.

Example of Invention

FIG. 1 is an overall block diagram of a text editing system as an embodiment of the present invention. This system includes an input unit 1 including a keyboard, a storage unit 2 for storing an input sentence, an operation storage unit 3 for storing the same correction content input from the input unit 1, and an edit control unit for controlling the entire system. 4. A display control unit that controls the display of sentences, a display unit, and a printing unit that prints out the sentences and outputs them as a hard copy.

FIG. 2 is a diagram showing an example of the key layout of the input unit 1.
The input unit 1 is provided with the following various keys in addition to the character keys for inputting English text.

Editing keys: 101 to 117 Cursor keys: 130 Other keys FIG. 3 is a flow chart showing the flow of processing of the editing control section 4 in the embodiment of the present invention. The edit control unit is in a main input waiting state (step S0) and waits for a key input until the user inputs some instruction from the keyboard. Then, the editing process according to the type of the input key is performed. For example, when the delete key is input, it corresponds to the case where the cancel key is pressed later. Therefore, first, the contents of the operation storage section are cleared (step S
11) Then, the correction flag is set to 1 to indicate that the correction has been made (step S12). Here, the character string in the range designated by the cursor is stored in the operation storage unit (step S
13). Next, the deletion process, that is, the character string in the range designated by the cursor is deleted (step S14), and the result is displayed (S15).

At this time, a deletion input waiting state (step S16) is entered, and the user waits for an instruction. Subsequently, when the delete key is pressed, the processing after step 13 is repeated. At this time, the contents of two delete keys are stored in the storage operation unit.
(Also, when a character key, a cursor movement key, or any other key is pressed, steps S21 to S26, S31 to S33, S, respectively.
The processes of 51 to S54 are similarly performed. ) It is again assumed that the deletion input is waited, and the cancel key is input here. The process proceeds to step S41. In this case, since the correction flag is 1, the contents of two deletion keys are read out from the operation storage section (step S42), and the deletion key 2
The state before the pressing of the turn is restored and displayed (step S43). After that, the operation storage section is cleared (step S4
4) The correction flag is set to 0 (step S45).

As described above, according to the present invention, it is possible to cancel the operation performed by the user in succession by one cancel operation. Therefore, for example, the contents deleted five times in a character unit can be canceled and repaired once. Because it can, the effect is great.

In the above embodiments, the keyboard is used as the input device, but a modification such as using a mouse or a tablet,
It can be applied to the editorial department of a machine translation system.

All such modifications and applications are included in the present invention.
