Trying to assign Ctrl+0 to Content Type: Disable, Ctrl+1 to Images, Ctrl+2 to documents etc. So… how do I do that, I don't see anything addressing Content Menu in the list of Commands? There's Context menu but obviously that's not it 
To select a particular format you can use command such as this:
Set CONTENTFORMAT="Music"I don't think there's a command to switch to "none" or "disabled", though.
You can give the Content-Type drop-down a hotkey, in which case you can push the hotkey and then use up/down to cycle through the modes (including none and disabled), though it's a bit clunky.
I suspect you don't really need this at all if it's tied to your other thread as you can do that stuff without using content type formats.
Yes, it's connected to that - I knew there must be an easier way to do this. Thanks leo!
