I created the Menu for my Matlab GUI which is "File" under which sub menus are Open, Save & Exit. When i clicked on the File Menu, it will list down the sub menu items Open, Save & Exit.
I want to assign a shortcut key for this file menu instead of clicking the file menu when i press the "Alt+F" it has the show the list down of sub menu items.I don't want to use the shortcut option provided by the Guide, i want to hard code that shortcut Key.
I have coded for the combination of the key detection (Alt+F) but which function/call back has to be used for the listing down of the sub menu items ?

Not sure what difficulties you're facing, but each menu item, no matter where it is in the hierarchy of menus and submenus, can be assigned a shortcut keystroke combination. So for example if you want File->Open to be control-O, you can specify that in the menu editor within GUIDE.

Its just like in Microsoft Word when we press Alt+F shortcut Key, we will get list of items in File Menu to select. Similarly when i press the Alt+F in my GUI, it has to show the list of the submenu items under File Menu.
As Shown in Image Below, i when click on File Menu, it will show the items in File Menu, same option i want to get by shortcut Key Alt+F

MATLAB is a cross platform app and unfortunately for us Windows users doesn't seem to follow all the conventions, like typing Enter to take the default button. I think it follows Java conventions more than Windows. If it doesn't respond to alt-F then you may just be a victim of differences between Java and Windows.
By the way, on my Windows 7 computer if you type Alt then down arrow (one after the other), the File menu drops down.
