Hot-key For Rotate

I am attempting to use the rotate tool that is accessible under drawing tools menu with right click. I use it often and am hoping to be able to hot-key it to my Wacom.
However i had a decent look and couldn’t seem to find it mapped anywhere.

Am i missing something? or does it just not exist


Figured it out using Mac os x custom keyboard maps.
Incase anyone else wants to have a go, you cannot use the Ctrl command in the hot-key. It will just trigger a right click.
