non-functioning keystrokes
 

I am using Excel and need to implement LINEST function and two sets
(so far) of keystrokes aren't functioning correctly.
I have plugging in the corded "Internet Navigator" keyboard both into
USB and port.

To make an array function, I need ctrl-shift-enter, but nothing
happens.

also:
The F2 key is supposed to be "edit" and all I get is "reply
email" (default).
The standard keyboard configuration doesn't have "edit" as a choice

Are these defined and/or set within Excel or externally?

thx
