What happened to Ctrl+Y to toggle Document Grid on and off?
I will add here that I really like the utility of having a toolbar with the different Snaps commands on it.
Those not only allow me to toggle the different snaps on/off, but they also provide at-a-glance indication of the status of the different snap modes.
The only thing I don't like about that is that the snap mode buttons don't "gray out" when "suppress all snaps" is in effect. I can live with that, and I rarely use the "suppress all snaps" toggle
I'm more likely to do the temporary, on-the-fly suppression of snaps by holding down the "Q" key.
