If you are talking about invoking code from a keypress (hotkey) in an Acess form then there is a 'keypress' event available in the form itself. Also there is a 'SendKeys' action in code available to execute code.
Thanks for the reply and sorry for my unclear question and my bad english.
I mean, for example: In microsoft word, you can set a bookmark of very long document by goto menubar, click insert-> bookmark and type the name of the bookmark.
Later you can jump into bookmarked place in that document by pressing F5 and clicking on the bookmark. And then you will be quickly redirected to the bookmarked place.
