Ext is an abbreviation of Extend.
It's an indicator that the range you're selecting should change when you click a
different cell.
Try clicking on any cell (say c3)
hit the extend key (- on the numeric keypad with numlock off, or hit F8)
then click on another cell (say f9)
Did you see how the selection changed?
You can toggle numlock on to kill the minus button on the numeric keypad acting
as the Extend key.
fyi: David McRitchie explains the statusbar:

When I use the minus button on my numeric keypad, "ext" appears in the bottom
right hand corner and the minus sign is disabled. Is this a macro? How do I
delete this? What does the "ext" mean?
