NAME

       fish_key_reader - explore what characters keyboard keys send

SYNOPSIS

          fish_key_reader [OPTIONS]

DESCRIPTION

       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:

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

       • -h or --help prints usage information.

       • -v or --version prints fish_key_reader's version and exits.

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:

       • press Control+C twice, or

       • press Control+D twice, or

       • type exit, or

       • type quit
