[Feature request] Add toggle keyboard key option from timeline to guide

Add toggle keyboard key for switching between timeline and guide. (Just like you can press T to switch between timeline and project bin.)

Use cases:
Fast switching between guides in order instead of skipping/jumping nearest guide depending on the playhead/cursor in timeline (for example, may jump over some guides if a clip is inserted is longer duration).

Also able to create automation scripts (using AHK or Actiona).
