Select all faces/verts?

These days I seem to do a lot of the following two operations:

• Select a bunch of adjacent faces in a single wall/floor/ceiling via Grow Selection with a low angle restriction, so that I can move or re-material a bunch of similar surfaces.
• Select all faces via Grow Selection without an angle restriction, so that I can weld any doubled verts.

I go back and forth between these two operations a lot, and it's tedious to keep alt-clicking the Grow Selection button to toggle the Restrict to Angle checkbox. Is there some key binding I'm missing to either Select All faces, so that I can leave the angle restriction in place on Grow Selection? Or maybe some modifier that makes Grow Selection toggle Restrict to Angle if an additional modifier is held?
