# 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.

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

  Displays help about using this command.

-V or --verbose

  Explain what sequence was received in addition to the decoded key.

-v or --version

  Displays the current fish version and then exits.

## Usage Notes

`fish_key_reader` intentionally disables handling of many signals. To terminate `fish_key_reader` in `--continuous` mode do:

- press ``ctrl`-`c`` twice, or

- press ``ctrl`-`d`` twice, or

- type `exit`, or

- type `quit`

## Example

    > fish_key_reader
    Press a key:
    # press up-arrow
    bind up 'do something'
