Commands fixes and updates

[spaghetti-coder]

Fixes #5330

Additional changes:

1. Added a few commands. Criteria for adding a command:
   1. Present in other similar editors, basically same as 1.2
   2. Often needed (one can argue that details is not one of them, but IMO point 1.3 is the exact reason)
   3. Hard to recall / too long to type
2. Fixed an issue from this comment
