FISH_KEY_READER(1) fish-shell FISH_KEY_READER(1) 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 se- quence. 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 se- quence. -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 stan- dard 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' COPYRIGHT 2023, fish-shell developers 3.7 Apr 14, 2025 FISH_KEY_READER(1)
