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 :ref:`bind <cmd-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 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.
|
|
|
|
- ``-V`` or ``--verbose`` tells fish_key_reader to output timing information and explain the sequence in more detail.
|
|
|
|
- ``-h`` or ``--help`` prints usage information.
|
|
|
|
- ``-v`` or ``--version`` prints fish_key_reader's version and exits.
|
|
|
|
Usage Notes
|
|
-----------
|
|
|
|
In verbose mode, 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 :kbd:`Control`\ +\ :kbd:`C` twice, or
|
|
- press :kbd:`Control`\ +\ :kbd:`D` twice, or
|
|
- type ``exit``, or
|
|
- type ``quit``
