Why don't some shortcut keys work?

[Miriam]

I've tried to assign the shortcut key ctrl alt i to get i with an accent on
it and even though it has been assigned when I go to use it in a word
document it won't work and Insert comes up from the tool bar...what can I do?

Sounds like you're not pressing Ctrl firmly enough; I would expect Alt+I to
select the Insert menu.
