Shortcut keys

Would it be possible for a future version to include a set of shortcut keys?

ie for a new folder, new rule, edit an existing rule and so on.

It is distracting and time-consuming to keep moving from keyboard to mouse if making/testing a new rule (let alone if you cannot easy use a mouse)?

I am aware that there is Keyboard Maestro, but I cannot see how that could distinguish between adding a new folder and a new rule to make a shortcut key (based on the image "+").

I'll consider this. As for Keyboard Maestro, I don't use it but the buttons do have different accessibility labels so there are ways to programmatically tell them apart. Not sure if KM uses that though.
