[Cin] Ctrl+! shortcut for Timecode doesn't work

[Igor BEGHETTO]

Maybe I wrong to write here because, probably, it depends by my system, 
but...

Using MMB (Middle Mouse Button) on an edit, in theTimeline, a pop-up 
menu come out. The last option is "Timecode Ctrl+!".
If I click on that option the timecode is set on the timebar of the 
Timeline correctly.
If I select the edit (a red frame is shown) and use Ctrl+! shortcut 
nothing occurs. Maybe, am I wrong to use that?
Can someone confirm, or not, please?
Thanks!
