Unless the right-click button is frozen, I'm sure you can use the mouse
right-click in Excel
Just hit the right-click button.
Now...........................the real issue
What are you right-clicking on and what doesn't happen for you?
Does the right-click not work at all or just under certain circumstances?
Maybe the right-click cell menu doesn't pop-up?
If you right-click on a Toolbar what happens?
More detail please.
