Excel shortcuts completely changed. Virus?

Hi!
beginner to mac...
please see images attached

on mac office, 30 days trial, all shortcuts have changed since yesterday... what happened?
is it a virus?

even the shortcuts in the customize keyboard are OK, for example "find".




Thanks for your help!

Your pics aren't working.

Corrected the links - you must use the shortcuts provided by tinypic for "Forums" when you post them in a forum.

1. It's not a virus

2. I'm unsure what the exact problem is. Are you saying if you press CMD+F is doesn't do anything?

thanks

Thanks for your answer

actually I had to restart the MBA and then it was working ok

as shown on the picture the usual shortcuts were not working even if internally well defined...

dont know what happened

Thanks

thanks again
