"Build Page" is one of the items you can add to your toolbar to compile just the ASPX page or ASCX control you are working on. Is there a keyboard shortcut for it?

              I always use Ctrl + Shift + B, which rebuilds the entire solution.
You could also configure your own keyboard shortcut by clicking Tools / Options / Keyboard and scrolling down to the Build options. (There's ones for Build.BuildPage or Build.BuildSelection...)

              Rebuilding the entire solution takes way too long.  I created a custom keyboard shortcut.  It's in Tools -> Customize -> Keyboard, not Tools -> Options -> Keyboard.
