I used to be able (in 4.4) to double-click on an event in the properties of a design window (using WinForms) and the event stub would be created and the cursor moved to the event stub. Now (in 5beta5) this doesn't seem to be so slick...
Double click on event property, nothing seems to happen; move mouse over design window, window switches to source view and cursor at start of file; scroll to bottom of file, there is the stub.
