Add shortcuts (Delaboratory 0.6) about delaboratory HOT 2 OPEN

OK for open/close/exit, but explain curves

in delaboratory to use curves you need to add curves layer
so I could make shortcut for combination of:
1) add curves layer
2) open curve editor for new layer
is that what you expect?

Yes. Thanks a lot.

On the whole, I think every "important" option should have its shortcut.
In my view, working with shorcuts is faster (no matter the software you take)
