[Bf-funboard] On hotkeys

Blender used to have *everything* in shortcuts, even before it had menus.
It's a productivity booster when you know the keys. But precisely
memorizing the keys is the problem. Most people have a rather small limit
of infrequent keys that can memorize. If you rarely use a feature you won't
memorize the key, but just the name (which you will search pressing space).

Another aspect to keep in mind is how reachable are those keys. The old
Blender rule was "one hand in the keyboard, the other in the mouse", and we
had (and still have) most of the frequent shortcuts in the left side of the
keyboard. I would move some keys of the right to the left, and use the
double tap funcion more.

Grouping similar functions = good.

Ctrl+shift+alt+U = bad.
