I have a usb keyboard that has a numberpad.
When I use the number pad in most situations, it works as expected (IE when I click the bottom 3 buttons, I get 123 in this web form).
However, when using vim (in a terminal window), in edit mode, if I type 123, I get:
s r q
I did not have this problem while I was using synergy to share the keyboard I had plugged into my linux desktop. (Edited - formatting)
