Click vs. Click on vs. Click at

Click is about pressing a mouse button to select a link or item on the screen. Use Click as a transitive verb that acts as an action verb and has a direct object — this means that no preposition is required after the verb.

Important

DO NOT use Click on and Click at.
Click in is acceptable but in other contexts. For example, click anywhere in the window.
