2. Description of the Related Art Conventionally, in an information processing device such as a Japanese word processor or a personal computer, when a character string in a document is edited (eg, copy, move, delete, etc.), the range of the character string to be edited is changed. May be specified. Normally, when designating a range to be edited, it is necessary to use a pointing device such as a mouse to designate the starting point and the ending point.

That is, for example, when copying the word "weather" in a sentence such as "Today is good weather" to another place, the user operates the pointing device to display "heaven" in "weather". "(Starting point) and" ki "
It is necessary to set the cursor to (end point).

[0004]

By the way, when designating a range to be edited, for example, in units of characters, units of words,
It is desirable to specify in units such as line units according to the purpose. However, in the conventional designation method, the pointing device must be operated to always designate the start point and the end point, and thus it is not possible to perform unit designation for each purpose as described above, resulting in poor editing efficiency. was there.

The present invention has been made in view of the above points, and has a plurality of range designation units such as a character unit, a word unit, and a line unit, and the range to be edited is arbitrarily switched. It is an object of the present invention to provide an information processing apparatus and a range designation method capable of designating a.

[0006]

According to the present invention, by optionally switching a plurality of range designation units such as a character unit, a word unit, and a line unit before or after designation of a position where a range is designated, Detects the range to be edited for each unit switched based on the specified position,
The detected edit target range is displayed in a specific display form.

As a result, when a character string in a document is edited (for example, copy, move, delete, etc.), the range of the character string to be edited is changed to, for example, a character unit, a word unit, or a line unit. It becomes possible to efficiently perform editing operations while designating units in accordance with the purpose.

Next, the range designation function in the embodiment will be described. FIG. 3 is a diagram for explaining a method of designating a range designation unit. This device uses "letter", "word",
It has six types of range designation units of “section”, “line”, “paragraph”, and “block”, and the edit target range can be designated for each of these units.

In the "character" unit mode, the edit target range is extended character by character. In the "word" unit mode, the edit target range is extended word by word (here, the transition of the character type is used as a delimiter condition). In the “bunsetsu” unit mode, the edit target range is extended in units of phrases (here, the punctuation marks or line break positions are used as the delimiter conditions).

In the "line" unit mode, the edit target range is extended line by line. In the "paragraph" unit mode, the edit target range is extended in paragraph units (here, the position of a line break is used as a delimiter condition). In the “block” unit mode, the edit target range is extended in block units (here, a rectangle formed by a start point and an end point).

Although the edit range is detected based on the position designated by the user, the range designation unit can be designated before or after the designation of this position. here,
The range designation unit can be sequentially switched using the mouse 15 or the keyboard 14. In the case of the mouse 15, the item 39a of the range designation unit of the status bar 39
Move the mouse cursor to and click. As a result, "character"->"word"->"section"->"line"->"paragraph"
→ The range specification unit switches in the order of “block”. In the case of the keyboard 14, the "F8" key is pressed. Each time the “F8” key is pressed, the range designation unit is switched in the order of “character” → “word” → “block” → “line” → “paragraph” → “block”.

FIG. 4 shows the switching state of the range designation unit. When the range designation unit is switched through the status bar 39 or the "F8" key, the edit target range is specified and displayed (for example, reverse display) for each unit.

In addition to this, when the mouse 15 is double-clicked at the place where the range is desired to be specified, the range can be specified in "word" units. Also, as shown in FIG.
When the mouse 15 is clicked while holding down the "Function 1 (Ctrl)" key, the range of the sentence where the mouse cursor is located can be designated in "bunsetsu" units. In addition, "Function 1 (Ct
If you drag while holding down the "rl)" key, the range can be expanded in units of consecutive sentences.

Further, the line ruler 42a can be used to specify a range in "line" units or "paragraph" units. In the line range designation, as shown in FIG. 6A, the mouse cursor is moved to the line ruler 42a for which the range is designated and the mouse 15 is clicked. In the paragraph range designation, as shown in FIG. 6B, the mouse cursor is moved to the line ruler 42a of the paragraph whose range is to be designated and the mouse 15 is double-clicked.

Next, the operation of the embodiment will be described. Figure 7
3 is a flowchart showing the operation of range designation processing. When the unit of range specification is specified by the method as described above,
First, the CPU 11 takes out the position where the range is designated (Yes in step S11). This is a process of extracting where on the document the position designated by the keyboard 14 or the mouse 15 is. The position may be designated before or after the range designation unit is designated.

If the "character" unit mode is designated (Yes in step S12), the CPU 11 detects one character at the designated position as the edit target range and displays it in reverse video (step S13).

When the "word" unit mode is designated (Yes in step S14), the CPU 11 determines the character type of the designated position (step S15). The word-based delimiter condition is to separate when the following character types differ.

Kanji / Hiragana / Katakana / Space / Alpha / Punctuation / Line feed The CPU 11 searches the document in the forward direction of the specified position, and the position obtained by adding +1 to the position where the character type has changed is the starting point of the range to be edited. It is detected (step S16). Next, the CPU 11 searches the document backward for the specified position, and detects the position -1 at the position where the character type has changed as the end point of the edit target range (step S17). In this way, when the start point and the end point of the edit target range in word units are detected, the CPU 11 reversely displays the edit target range (step S18).

When the "bunsetsu" unit mode is designated (Yes in step S19), the CPU 11 uses the punctuation mark or line feed as a delimiter condition, searches the document forward of the designated position, and finds the position where the punctuation mark or line feed occurred. The +1 position is detected as the start point of the edit target range (step S2
0). Next, the CPU 11 searches the document backward for the specified position, and detects a position minus -1 at the position where there was a punctuation mark or a line break as the end point of the edit target range (step S2).
1). In this way, when the start point and the end point of the edit target range in units of phrases are detected, the CPU 11 reversely displays the edit target range (step S22).

When the "line" unit mode is designated (Yes in step S23), the CPU 11 detects one line including the designated position as an edit target range and displays it in reverse video (step S24).

When the "paragraph" unit mode is designated (Yes in step S25), the CPU 11 uses the line feed as a delimiter condition, searches the document in the forward direction of the designated position, and adds +1 to the position where the line feed occurs. It is detected as the start point of the edit target range (step S26). Next, the CPU 11 searches the document backward for the specified position, and detects a position minus -1 at the position where the line is broken as the end point of the edit target range (step S27). In this manner, when the start point and the end point of the edit target range are detected in paragraph units, the CPU 11 reversely displays the edit target range (step S28).

When the "block" unit mode is specified (Yes in step S29), the CPU 11 edits the rectangular range formed by the start point and the end point based on the positions previously specified as the start point and the end point of the block. It is detected as a range and this is highlighted (step S30).

In this way, the edit target range can be designated for each of a plurality of units. Therefore, when editing a character string in a document (for example, copy, move, delete, etc.), the range of the character string to be edited can be changed according to the purpose, for example, in character units, word units, or line units. It becomes possible to perform editing operations efficiently while designating in units.

In the above embodiment, the input character string is converted into Kana-Kanji characters, and therefore, in the "word" unit mode, not the original word but the transition of the character type is used as the delimiter condition. By using the information at the time of conversion (the result of the syntax analysis of the input character string, the information of the Kana-Kanji conversion dictionary, etc.), the edit target range can be detected using the original word as a delimiter condition. Similarly,
Even in the “bunsetsu” unit mode, the editing target range can be detected using the original bunsetsu as a delimiting condition by using the information at the time of kana-kanji conversion.

[0044]

As described above, according to the present invention, a plurality of range designations such as a character unit, a word unit, and a line unit can be performed before designating a position for performing range designation or after designating a position for performing range designation. By selectively switching the unit, the range to be edited is detected for each unit switched based on the specified position, and the detected edit range is displayed in a specific display form. When editing a character string in a document (for example, copy, move, delete, etc.), the range of the character string to be edited is a unit according to the purpose, such as a character unit, a word unit, or a line unit. It becomes possible to efficiently perform the editing operation while designating with.
