fish_key_reader [OPTIONS]

fish_key_reader is used to study input received from the terminal and can help with key binds. The program is interactive and works on standard input. Individual characters themselves and their hexadecimal values are displayed.

The tool will write an example bind command matching the character sequence captured to stdout. If the character sequence matches a special key name (see bind --key-names), both bind CHARS ... and bind -k KEYNAME ... usage will be shown. Additional details about the characters received, such as the delay between chars, are written to stderr.

The following options are available:

Usage Notes

fish_key_reader intentionally disables handling of many signals. To terminate fish_key_reader in --continuous mode do:
