Choose the Property You Want to Control<br \/>\nFirst, select the layer and property where you want to apply the expression. For example, if you&#8217;re animating a bouncing ball:<br \/>\n\u25cf Click the layer in the timeline.<br \/>\n\u25cf Press `P` (Position), `R` (Rotation), `T` (Opacity), or the relevant shortcut.<br \/>\n<img loading=\"lazy\" decoding=\"async\" src=\"\/wp-content\/uploads\/replace\/fd2721b8f00806dedbd4e90e36f616b9.png\" alt=\"How to Add Expressions in After Effects (3 Simple Steps)\" width=\"769\" height=\"434\" class=\"alignnone size-full wp-image-1112\" \/>This reveals the property, setting you up for the next step.  <\/p>\n<p>2. Activate Expressions with a Shortcut<br \/>\nNow, enable expressions:<br \/>\n\u25cf Hold `Alt` (Windows) or `Option` (Mac).<br \/>\n\u25cf Click the stopwatch icon next to the property.<br \/>\n<img loading=\"lazy\" decoding=\"async\" src=\"\/wp-content\/uploads\/replace\/e0eee3a27df0597f2a1498290b9953cc.png\" alt=\"How to Add Expressions in After Effects (3 Simple Steps)\" width=\"769\" height=\"434\" class=\"alignnone size-full wp-image-1113\" \/><br \/>\nA text field will appear with default code (like `transform.position`), meaning it\u2019s ready for your custom expression.  <\/p>\n<p>3. Enter or Paste Your Expression<br \/>\nYou can now type directly into the field or paste a pre-written expression.<br \/>\nTo paste:<br \/>\n\u25cf Click inside the expression box.<br \/>\n\u25cf Press `Ctrl + V` (Windows) or `Cmd + V` (Mac).<br \/>\n\u25cf Confirm by hitting `Enter` (on the numpad) or clicking outside the box.  <\/p>\n<p>That\u2019s it! Your expression is active and will update dynamically.<br \/>\n<img loading=\"lazy\" decoding=\"async\" src=\"\/wp-content\/uploads\/replace\/4a603e1676aee50c6b36422cdadd31b6.png\" alt=\"How to Add Expressions in After Effects (3 Simple Steps)\" width=\"769\" height=\"434\" class=\"alignnone size-full wp-image-1114\" \/><br \/>\nQuick Example: Auto-Wiggle Loop<br \/>\nWant a smooth, randomized movement without keyframes?<br \/>\nTry:<br \/>\nwiggle(2, 30)<br \/>\nThis makes the layer wiggle 2 times per second with 30 pixels of movement\u2014effortless animation at your fingertips.  <\/p>\n<p>Why Use Expressions?<br \/>\n\u25cf Saves time (no manual keyframing).<br \/>\n\u25cf Creates dynamic links between properties.<br \/>\n\u25cf Allows for complex motion with minimal effort.  <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Expressions in After Effects are a game-changer\u2014they automate animations, sync movements, and save you from endless keyframing.
