Multiple Buffer Editing

Mark text for copying using Alt + ^. Move the cursor to the end of the desired text and
press Alt + 6 to copy. Paste using Alt + U.


Syntax Highlighting

Enable syntax highlighting with -Y flag: nano -Y <language> filename. Replace <language> with the language identifier (e.g., sh, python, c).


Spell Checking

Toggle spell checking with -S flag: nano -S filename. Use Ctrl + T to switch spell checking on/off.


Line Numbering

Display line numbers using -c flag: nano -c filename. Line numbers appear on the left side.


Regular Expression Search and Replace

You can use regular expressions (regex) to search and replace text efficiently. Follow these steps:

  1. Enable regex mode: Press Alt + R to activate regex mode.
  2. Enter the search pattern: Type the regex pattern into the search field.
  3. Enter the replacement text: Type the text you want to use for replacement into the replace field.
  4. Search and replace:
    • Press Alt + W to replace the current match.
    • Press Alt + A to replace all occurrences in the document.

Example Usage

  • Search: To find all email addresses,
    use the regex: \b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Z|a-z]{2,}\b
  • Replace: To replace all found email addresses with example@example.com, enter this in the replace field.

Tips

  • Save before replacing: Always make a backup of your document before performing extensive replacements.
  • Test your regex: Test your regex on a small section of your document first to ensure it works as expected.
  • Use groups: Utilize regex groups (e.g., (...)) to reuse specific parts of your match in your replacement text.

Good luck with using regular expressions for efficient search and replace!
