There's a couple of basic, but very handy functions that appear to be missing when coding passages in Twine, and those are 'Ctrl Z' for undo and right-click 'copy/cut/paste'. I appreciate they are under the 'edit' link at the top of the window, but 'undo', at least does not appear to work.
I make a lot of mistakes when coding and not being able to undo something is proving quite problematic. So much so that I find myself copy/pasting blocks of code into notepad before I make any changes, just in case I need to revert back. Even this is a pain, though, as the only option is 'Ctrl C / V' or to use the links.
Is there a reason these functions are not there?
