Key Mapping
Key mapping assigns (maps) a key sequence to a physical key or key combination.
Readline Key Mappings
The following key bindings are used when opening the Readline command line buffer in an editor.
C-x
The key sequence C‑x is mapped to the escape sequence \x18.
C-e
The key sequence C-e is mapped to the escape sequence \x05.
Mapping Your Own
If the key sequence C-x + C-e (Windows/Linux) or Cmd-e (macOS) is not active or conflicts with an existing shortcut, you can manually configure the mapping. To do this, map the escape sequence \x18\x05 to your preferred key or key sequence within your terminal settings.
