It would be easy and useful to put the most-commonly-used keyboard shortcut characters (such as ⌃⌥⇧⌘⎋⏏⌫↑⇡↖⇞⇥, and perhaps others — see [here](http://pastie.org/4011) for a list, which you can also place at `~/Library/Key Bindings/DefaultKeyBinding.dict` to type these characters easily) somewhere on the page (perhaps in the editing help, or discreetly in the footer?) so people could copy and paste them when writing questions/answers if they don't have an easy way to type them.
