You could just create a simple user macro. (Though it's hardly surprising that people try to sell expensive plugins on here instead of just copy/pasting a simple script as an answer.)

To save it as a user macro, go to Administration -> User Macros.
To use it, edit a page, choose insert macro, then select the name you've given it.
