The System Keyboard preference pane lets you set menu item shortcuts for any application. In the Keyboard Shortcuts tab, select Application Shortcuts and hit the plus button to add a new application to the list. (You may have to use the "Other" item in the Application pulldown to get to OG.) Then name the menu item and enter your shortcut. I just tried it for OG's Zoom In and it works fine.
