Clique is a "click-casting" addon, very easy to use, which allows us to assign skills to mouse clicks and combinations of these with keyboard modifiers. Its operation is similar to that of a mouseover macro. That is, we can cast our spells on Grid or another frame addon directly by clicking on the desired target, without having to select it previously. This adds reaction speed, especially when it comes to instant spells that you have to use while moving, although it can be used with spells of all kinds.
This addon has undergone slight changes with the release of patch 4.0.1, notably improving its appearance and configurability. In addition, it also better detects different types of mice. Therefore, I have decided to update the guide by taking new screenshots and adding explanations as necessary.
