curs_extend - Linux
Overview
curs_extend is a Linux utility used to extend the capabilities of the cursor keys on a terminal emulator. It allows users to perform advanced cursor movements and selections, making text editing and navigation more efficient.
Syntax
curs_extend [options]
Options/Flags
- -o: Extend cursor movements beyond the end of the line.
- -e: Enable extended cursor selection.
- -m: Enable multiple cursor selection.
- -c: Enable character selection.
- -w: Enable word selection.
- -l: Enable line selection.
- -s: Enable search mode.
Examples
Extend cursor movements beyond the end of the line:
curs_extend -o
Enable multiple cursor selection:
curs_extend -m
Select a word using extended cursor selection:
curs_extend -e
t<ctrl-space>h<ctrl-space>e
Search for a specific string in search mode:
curs_extend -s
/mysearchstring
Common Issues
- Cursor jumps to the beginning of the line when moving beyond the end: Disable the -o option to prevent this behavior.
- Selection does not work properly: Ensure that the correct selection mode is enabled (e.g., character, word, line).
