Trigger another addon? Rated 5 out of 5 stars

This addon is a great time-saver.
Question: Is it possible to make it so a gesture triggers another addon?
For example, I want to read an article, make a gesture, and Clearly (addon from Evernote, similar to Readability) is activated.
Gomita, will it be difficult to implement this feature?
