# Objective

- Fix support for alt-f5 in terminal and add support for ctrl-alt-key

## Solution

- Fix `crates/terminal/src/mappings/keys.rs`.

## Testing

- Did you test these changes? If so, how? Added a unit test, and test
the built zed with fish_key_reader to check that the keys are indeed
recognized.
- Are there any parts that need more testing? No
- How can other people (reviewers) test your changes? Is there anything
specific they need to know? Fish has fish_key_reader which can check the
keys that it recognizes. Not sure about other shells. `cat | xxd` can be
used to confirm the exact received key codes.
- If relevant, what platforms did you test these changes on, and are
there any important ones you can't test? Tested on Linux only.
