FR: Keyboard Shortcuts for Commands

[z-ai-lab]

Is your feature request related to a problem? Please describe.
Mouse-only command execution can be slow and less accessible for keyboard-centric users.

Describe the solution you'd like
Implement customizable keyboard shortcuts to execute commands; for instance, press key p to choose the Proofread command.

Describe alternatives you've considered
Continuing with mouse-only interaction is less efficient.

Additional context
This improves workflow speed, accessibility, and caters to power users.

Good idea; will implement after the stable release. If you're interested in creating a PR, that would be very welcome.
