Changing the snap option for the grid?

This probably has a ridiculously easy answer, but how does one change the option of the snapping to the grid?
Right now, in my lower right hand corner of Hammer, there's that small taskbar (well, a part of it) that says "Snap: On Grid: 1". I want to turn it off so I can fix this:

After that is corrected, I'd like to turn it back on. I've done it before on accident, and couldn't get it to change back and when I load the sdk file for cs_militia it says "Snap: Off" and there is no grid visible.

there's a snap toggle button somewhere on the toolbar, but you can also hold down alt to temporarily disable snapping, and allow finer rotations of objects too.

the [ and ] keys decrease and increase the grid sizes, respectively.

This ALT key thing is amazing.

Hahaha, thanks, fishy.
