Q:

SHIFT+7 = ALT - bizarre behaviour

Suddenly, when using excel, SHIFT+7 has begun to produce the behaviour of the ALT-button in that it highlight my ribbon shortcuts.  As SHIFT+7 is what I need to produce the character "/", this is a real annoyance.  Keyboard layout is as it should be (Norwegian).  Anyone knows if this is a bug, intended feature or an option I can somehow disable? 
This is the only SHIFT-combination that creates this type of behaviour, and it only happens in Excel, not Word. 
Getting ready for some "voted down" here, but this is has really baffled me, so have to ask. 

A:

This is by design, the / acts like Alt. ( Thay say it has something to do with Lotus compatibility.) 
You can go to the Options, Advanced, find Lotus compatibility, and turn off this feature.
