Grouping layers are a great way to create a more manageable overview, as you can both toggle close groups as well as animate on a group level 😄
As the shortcuts are a little different let's look at how you group layers on both PC and Mac.
Group layers on PC:
Go into your template
Hold down shift
Click on the layers you want to group
Press CTRL+G
Group layers on MAC:
Go into your template
Hold down shift
Click on the layers you want to group
Press CMD+G
Also see this article of how you can rename layers, to make your layer menu even more manageable #stayorganized ☀️
Happy layering 🚀
