What keyboard shortcut reveals the effect controls on a selected layer?

The keyboard shortcut that reveals the effect controls on a selected layer in Adobe After Effects is indeed the key 'E'. This shortcut provides a quick and efficient way to access the effects applied to any selected layer without navigating through menus, allowing for a streamlined workflow when working on projects.

When you press 'E', After Effects shows all the properties related to the effects that you have added to that specific layer. This is particularly useful for animating, tweaking parameters, or adjusting effects in real time, making it easier to refine your composition.

Using shortcuts like 'E' is essential for speeding up the editing process, enhancing efficiency, and enabling quick edits while working on complex projects. This direct access helps maintain focus on the creative aspects without significant interruptions.
