Easier stopwatch setting not in Help

[BioBox]

The stopwatch is great, but it's a pain to have to type stopwatch --h:--m:--s everytime I want to reset it.
My initial plan was to make it easier myself, but after looking through the code I found that you're totally allowed to enter the fields seperately, it's just that the help system doesn't give you any indication of this.

Could you please edit the help file to let the rest of us know?
Also, could you write in an abbreviation to that command so we can type in sw instead?
