In this short post, I will show you how to quickly hide timeline properties in Adobe After Effects.
Step 1: Press and hold ALT + SHIFT on a PC or OPT+SHIFT on a Mac.

Step 2: Click on any property that you want to hide while holding ALT + SHIFT on a PC or OPT + SHIFT on a Mac.
You can also hide groups the same way.
If you want to get those properties and groups back, all you have to do is first click on the toggle menu to hide all remaining properties and groups.
Next, CTRL + LEFT CLICK on a PC or CMD + LEFT CLICK on a Mac to bring them all back.
I hope you found this tip useful!
