I was playing around with < key [ ] pressed? > and I found out that you can detect either shift key with this:
Is it possible to differentiate between left and right shift?
Thanks.
Welcome to Snap, first of all! Second of all, what would you need 2 shift key differentiations for? We give you some helpful alternatives for the shift keys. That, or @bh or @jens could implement that.
There's also the javascript block, (which you should use only for good,) that can probably detect that sort of stuff.
