How would you enter
retsubkcolB
spelled backwards into the comment box below and press the "Add comment" button (nothing will happen, as there's only 11 letters) using at most 10 clicks in total?
You should end up with something like this:
Requirements:
You may only use a mouse - Right-click, left-click and cursor movement.
You may only stay on this page - Imagine this page locked into your screen. No new tabs, new windows, minimizing the current window, etc.
No userscripts or extensions - Just your standard browser on standard settings.
Note: This is a PC puzzle, so it might not work for phones.
EDIT
I failed to mention that you must assume this as a fresh puzzle, meaning you cannot incorporate later comments, answers, etc. into your solution.
