Button for Context menu

Is there a way to add a button to DOpus that when clicked will bring up the list of context menu "Open With" commands? I'd like to find an easier way to choose "Open With a program" when a file is selected (e.g. options for Photoshop, Picture viewer, etc. for jpeg files) than to right click and wade through an increasingly cluttered context menu.

FileType OPENWITHMENU is the command you want.
