Thank you for using our services.
Part of what you are suggesting is already available in Sitefinity. The editor tools have shortcut keys. You can gather more information on RadEdtior keyboard shortcuts here
. As for the shortcuts for the I'm Done and Cancel buttons, this is a good suggestion and we will discuss it for our next releases.
I hope that this information answers your questions.
