Nobody forced you to use this Rated 4 out of 5 stars

You should be well informed by the description of this add-on before using it. Nobody can force you to abandon your shortcut keys and keyboard shortcuts. It's just convenient for people who prefers or uses mouse a lot, or when keyboard is not easily accessible (ex. when your fingers are full of potato chips).I wonder if I can use this well with my touchpad on the laptop though.

This review is for a previous version of the add-on (1.5.1).
