[FEATURE] Control using the keyboard / accessibility

[dbmann1]

Is your feature request related to a problem? Please describe.
I have seen that you have already dealt with the topic of accessibility in (#124). Even though I'm not visually impaired and don't rely on a screen reader, I love it when software can also be operated using the keyboard.

Describe the solution you'd like
It would be desirable if all knobs, switches and buttons could be controlled with keyboard commands.

Describe alternatives you've considered

Additional context

Can this be done via MIDI? (Key triggers MIDI command, MIDI command is heard by the plug-in and does what you want)

If so, then it may make sense to start with #451 and go from there.
