Would be useful to provide shorthands for common keys

[baseten]

We're migrating over from Mousetrap and have a key binding against ?.

It doesn't seem possible to use ? in KeyboardEventHandler's handleKeys- we have to use shift+/ instead. Is this intended behaviour?

Apologies, this works with keypress - that said Mousetrap has quite a nice feature where it would autodetect the required key event depending on the key combo. Could be a useful feature?
