Text Editing: Cut, Copy, Paste, Undo, Redo (टेक्स्ट एडिटिंग)

Text editing allows you to alter, correct, rearrange, and duplicate words, sentences, and paragraphs without having to retype them from scratch.

The Clipboard (क्लिपबोर्ड) is an invisible temporary storage area in RAM managed by the operating system that holds text or graphics you have cut or copied.

1. Text Selection Techniques

Before modifying text, you must select (highlight) it:

• Single Word: Double-click on the word.
• Entire Sentence: Triple-click anywhere inside the sentence (in Writer) or Ctrl + Click (in Word).
• Entire Paragraph: Quadruple-click (4 clicks) on the paragraph.
• Entire Document (Select All): Ctrl + A.
• Continuous Selection: Click at the start, hold down the Shift key, and click at the end.

2. Cut, Copy, and Paste Mechanics

Keyboard Shortcuts:

• Copy (कॉपी): Ctrl + C (Leaves original text intact).
• Cut (कट): Ctrl + X (Deletes original text from source).
• Paste (पेस्ट): Ctrl + V (Inserts clipboard contents at cursor position).
• Paste Special (पेस्ट स्पेशल): Ctrl + Shift + V (Writer/Calc) or Ctrl + Alt + V (Word). Allows pasting unformatted plain text without carrying over unwanted internet formatting.

3. Undo and Redo: Reversing Mistakes

Humans make typing and formatting mistakes. Word processors provide a safety net:

• Undo (अनडू - पूर्ववत करें): Reverses your last action, restoring text or formatting to its previous state.
• Shortcut: Ctrl + Z
• Redo / Repeat (रीडू - पुनः करें): Re-applies the action that was just undone by Undo.
• Shortcut: Ctrl + Y

4. Non-Printing Characters (विगेटिंग मार्क)

Sometimes text looks misaligned because of extra spaces or accidental Tab presses. In LibreOffice Writer, you can toggle Non-Printing Characters on and off:

• Shortcut: Ctrl + F10
• Displays visual symbols on screen (which do not print on paper):
• Spaces appear as dots (·).
• Enter / Paragraph breaks appear as pilcrow signs (¶).
• Tab keys appear as small right arrows (→).
