I love how newer versions of PHPEd allow you to CTL-Click a function to Find Declaration. Could such functionality be extended to Open File at Cursor so that we can CTL-Click a filename within an include statement?

I would opt for an even more consistent way all around the application.
- Add an open file item to the menu of the code navigator when you right click on it, and open it with ctrl-click
- Why not add the ctrl-click also to the predefined building php functions. Now I still have to press ctrl-f1.

Just ctrl-click on all!!!

You sir, have some great ideas .

Although I should note that if you want to get help on php builtin functions you need only click on it and hit F1. I find this to be rather convenient/easy and might keep things cleaner than having CTL-CLICK work on builtin functions. Just IMO.
