Programmatically opening procedure windows

Is there a way to programmatically open a procedure window? I basically want to enact the menu item 'Go to myFunction' that you can use by right clicking on a function call within a procedure window or in the command line. 

The context is a panel that has a drop down menu with different user defined functions. I'd like to have a button next to it that can pull up the .ipf of the selected function, so the user can easily navigate to that function's code.   

Thanks for any help.
