Which is probably known to every body but me, but there's a block of 6 buttons between the keyboard & the numbers keyboard of which the middle 2 are Home & End, pressing Home will take you straight to the top of any thread or document & pressing End will, (guess what :0) take you straight o the end.
Page Up & page Down is only like using the mouse wheel, though it might be useful for someone with arthritic hands.
ha, I never knew that. I suppose I don't often want to jump straight to the start or the end, I usually scroll to look at the stuff in the middle, so I've not really needed it. Thanks for the tip, anyway.
