like the subject line says, is "DP" short for Depth of field preview button? also, is there a way to intercept the AF point button to use with LUA scripts? I think this button would be ideal since it is the only button (to my knowledge) that isn't currently utilized by some other feature of ML. How about "silent shooting touchpad" ? I'm still learning this body, but aparrently the 5d3's set dial has a four way capacitive touch pad built in!

I'm surprised this was not already implemented (perhaps the author did not own a body with these buttons?)

also, what is "flash movie" ? is this the button that pops up the built in flash on small bodies?
