       fish_key_reader -- explore what characters keyboard keys	send

       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

       The following options are available:

       o -c or --continuous begins a session where multiple key	sequences can
	 be inspected. By default the program exits after capturing a single
	 key sequence.

       o -d or --debug-level=DEBUG_LEVEL enables debug output and specifies a
	 verbosity level (like fish -d). Defaults to 0.

       o -D or --debug-stack-frames=DEBUG_LEVEL	specify	how many stack frames
	 to display when debug messages	are written. The default is zero. A
	 value of 3 or 4 is usually sufficient to gain insight into how	a
	 given debug call was reached but you can specify a value up to	128.

       o -h or --help prints usage information.

   Usage Notes
       The delay in milliseconds since the previous character was received is
       included	in the diagnostic information written to stderr. 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:

       o press Ctrl-C twice, or

       o press Ctrl-D twice, or

       o type exit, or

       o type quit
