[Feature] Shortcuts/aliases for commands

Hi team,

I'm a newcomer to the Q CLI but already had the chance to get a lot of value out of it so thank you so much for the great work.

I like to use the /editor command a lot and was wondering if there could be some faster way of doing it.

I could think of two ways to do it and wanted to get some feedback:
- Have command shortcuts e.g. `/e == /editor`
- Or have a Ctrl-E (or something else) mapped to /editor

I assume other users might have their own favorite commands so maybe we can think of a more scalable way to handle this.

In any case, I'd be happy to contribute with the implementation a potential solution.
