To quicky switch between a-rrows and t-ext and back again to the selection tool.
Especially important since the "bigger icon improvement" has been put on hold. It's tedious having to aim at the tiny icons on a hi-res screen. Tool-shortcuts (one letter please) would make it easier. They should not respond when in TextBox or Caption Mode (naturally). These modes must be exited first (ESC) before A-rrows and F-rames etc work again.
