MS-Access: hotkey to display a message box

I need particular users the ability to lock a record on a form, but I don't need anything too serious such as setting different security settings.

Idea: I would like to be able to have a certain keydown combination (ex: ctrl+alt+M) to open a message box. (I'm trying to avoid making a small form because all I need returned is either yes, no, or cancel)

I have been looking around, but I'm not sure where to start with this one... Your feedback is always 开发者_开发问答appreciated!

Have you considered AutoKeys macro?

Perhaps you wish to make it form specific?
