How to edit a vbproj file

[Bob Altman]

I have a solution that contains a bunch of VB projects. I need to edit the text
of the vbproj files to fiddle with build events in a way that the IDE doesn't
let me do directly. Is there any way to ask the IDE to open the text of a
vbproj file that is part of the solution I'm currently working on?

TIA - Bob
