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'
