Other programs use Cmd-Shift-S for "Save As". With Hype, this creates a copy of the document.
Please change the keystroke to Cmd-Shift-N or Alt-Shift-N. This makes a whole lot more sense. S is always associated with some form of save while N is always associated with something new.
Frankly, when rushing to get a job out the door, I may not stretch my index finger far enough and I sometimes accidentally hit Cmd-Shift-S instead of Cmd-Shift-E. I then have to come to a screeching halt. Wait a couple of seconds for the document to be duplicated, then kill the document.
I would much prefer that Cmd-Shift-S did absolutely nothing.
