It's incredibly annoying in Outlook. Every other Microsoft product I've used like Word supports the key-combo, but of course Outlook has to be different.
Haha, I wish they'd thought of that before they implemented the ribbon to replace the menu bar. I can't imagine how many hours of productivity were lost for people dealing with that change.
you'll be happy to know that a lot of the ribbon is going away in favor of small buttons with icons on them, and people are losing their minds over it. so no matter what Microsoft do, millions of people are gonna bitch about it and complain for years and years.
