[CinCV] simple shortcut question

Hi there, just a simple question on shortcuts:

Is there any keyboard shortcut to toggle between cut-and-past editing
to/from drag-and-drop editing?

It's just that I've realized (after some years of use) that this is probably
the intarface funcion I lose most time with while editing in general and I
don't remeber reading about a feature like this... I also thought if it
could be a shift+key or ctrl+key shortcut I'm not aware of.

<<<This one comes as an add but I'm pretty sure there isn't: a shortcut to
toggle between "play all frames" on or/to off?>>>

thanks!
