I think my computer's too old/doesn't have the keyboard plug-inability but maybe it does the mouse! I'll have to try that, thanks for the idea.

Although, now I think of it, I use the laptop in my lap :-) in a big old chair with my foot on its footstool, there's no room for a mouse, no table. If I weren't so lazy, I could use the desktop upstairs. And this works okay, just has the "wrong" button working and I have to have the good one not work a couple times and then I switch, LOL.
