what’s the keyboard shortcut in Photoshop 7 for switching between Brush Size and Precise cursor types?

I keep pressing my keyboard by accident, and then my cursor changes (eg when using the brush tool) from Brush Size mode to Precise mode, and then I get stuck because I can’t see the size of my brush! And then i have no idea how to switch it back…but then sometimes it does so w/o me doing anything. Ideas?
