# Use The Readline Keybindings Anywhere
|
|
|
|
There are these features of the "shell" that I've often heard called _emac
|
|
keybindings_. These are things like `ctrl-a` (move the cursor to the beginning
|
|
of the line) and `ctrl-e` (move the cursor to the end of the line) that I use
|
|
every single day. There are several others that are in my heavy rotation,
|
|
however, I learned about a couple more reading through [Shell Tricks That
|
|
Actually Make Life Easier (And Save Your
|
|
Sanity)](https://blog.hofstede.it/shell-tricks-that-actually-make-life-easier-and-save-your-sanity/).
|
|
|
|
These are [Readline commands](https://www.gnu.org/software/bash/manual/html_node/Bindable-Readline-Commands.html)
|
|
(or keybindings) which means they are supported by anything that uses Readline
|
|
under the hood. So while you might be using these to great effect in `bash` and
|
|
`zsh`, you should look for other places they are available.
|
|
|
|
A non-exhaustive list includes:
|
|
|
|
- Ruby's `irb`
|
|
- Python's `python`
|
|
- Node.js' `node`
|
|
- PostgreSQL's `psql`
|
|
- Claude Code
|
|
|
|
And many more similar REPLs and command line tools.
|
|
|
|
Try these keybindings out in one of your favorites and when you're done hit
|
|
`ctrl-c` to exit out of it.
|
|
|
|
PS. subsets of these keybindings are sometimes supported in unexpected places
|
|
like the Chrome URL bar.
