RubyMine key shortcuts convention

This might be a very stupid question, for which I don't know the answer.

What is this key in the MAC shortcuts? "↖"
I tried every single key in that combination Related File... (⌘⌥↖) but without luck.

Another key that I don't know is this one: "⎋". If somebody can post a list of these symbols and corespondent keys, would be great.

Thanks!
