NAME¶
fish_key_reader - explore what characters keyboard keys send
SYNOPSIS¶
fish_key_reader [OPTIONS]
DESCRIPTION¶
fish_key_reader is used to explain how you would bind a certain key sequence. By default, it prints the bind command for one key sequence read interactively over standard input.
If the character sequence matches a special key name (see bind --key-names), both bind CHARS ... and bind -k KEYNAME ... usage will be shown. In verbose mode (enabled by passing --verbose), additional details about the characters received, such as the delay between chars, are written to standard error.
The following options are available:
- -c or --continuous
- Begins a session where multiple key sequences can be inspected. By default the program exits after capturing a single key sequence.
- -V or --verbose
- Tells fish_key_reader to output timing information and explain the sequence in more detail.
- -h or --help
- Displays help about using this command.
- -v or --version
- Displays the current fish version and then exits.
USAGE NOTES¶
In verbose mode, the delay in milliseconds since the previous character was received is included in the diagnostic information written to standard error. This information may be useful to determine the optimal fish_escape_delay_ms setting or learn the amount of lag introduced by tools like ssh, mosh or tmux.
fish_key_reader intentionally disables handling of many signals. To terminate fish_key_reader in --continuous mode do:
- press Control+C twice, or
- press Control+D twice, or
- type exit, or
- type quit
EXAMPLE¶
> fish_key_reader Press a key: # press up-arrow bind \e\[A 'do something' > fish_key_reader --verbose Press a key: # press alt+enter
hex: 1B char: \e ( 0.027 ms) hex: D char: \cM (or \r) bind \e\r 'do something'
