Tool selections should always have shortcuts. You don't want to break the
builder's flow by forcing them to repeatedly interact with the UI when they
don't have to. Dropping it entirely would be a bad idea.

My choice of CTRL+A was that it's simple (you can do it with only your left
hand on a QWERTY keyboard), it doesn't actually interfere with other parts
of the UI (that is, you can't select inworld prims and the UI
simultaneously), and all the prim manipulation shortcuts are non-standard
anyway. A bit of a copout, I know, but the list of open shortcuts was tiny.
I'm sure you could steal a different key combo from one of the windows
(which don't need a shortcut nearly as much anyway). CTRL+G would probably
be a better option, looking back.
