I'm slightly amazed at the existence of RISC OS users who don't know all of this already. One thing that nobody has mentioned yet is that in RISC OS 5 and 6, you can ADJUST-click on the 'back' tool icon of a window in order to bring it to the front. I find that one really useful! (I think it originated in Director, and I am surprised that Acorn did not think of it themselves.)
