selecting from a list with aid of keyboard

[Kurt Kaufman]

I know that this issue was addressed sometime in the
last couple of years, but I can't seem to locate it:

When selecting a single line from a scrolling list
(this being a Rev list, not the OS file selection
box)it would be useful to enter 1-3 keys to have the
field scroll to the entered letter, or letters. 

Could someone point me to the discussion of that
subject?

Thanks, Kurt
