Over time, I have found several key-bindings that access Excel
functionality that are not documented anywhere that I have looked. I do
not remember all of them offhand, but here are a few:

CTRL-SHIFT-< = Fill Down
CTRL-SHIFT- = Fill Right
CTRL-ALT-L or R Arrow = Goto previous (next) selection area in multiple
area selection.
CTRL-Insert = Copy


Does anyone know of any other rarely used Excel keyboard bindings?
