How do I remove MID on top of the units? (red numbers)

[someonemustgethurt]

In editor mod, the MID is always visible on top of all of the units. I see a red number on all the soldiers, tanks, and other entities whether in f1, f2, f3 or test mode. I've turned this off somehow before but I can't seem to find how to do it now. So is there a command or hotkey that turns it off, thanks.
