Apply an expression using a keyboard shortcut
I’m trying to find a way of quickly applying some of my regularly used expressions to various properties by using a keyboard shortcut, or by some other trigger (avoiding the need to click using the mouse). Is this possible? I have a Stream Deck, as well as KBar and I also use Quiver to manage my expression library, but I’m looking for a way to instantly applying an expression to the selected property. Is this possible?

So I found how to apply an expression in After Effects using a shortcut.
You will need to use automation software to create a macro (performs multiple steps one after another), and control your shortcuts.
Automation software options
Mac: Soundflow (highly recommended), Keyboard Maestro, Stream Deck
Windows: Auto Hot Key, Stream Deck
These are the steps I included in my macro, on Mac:
– Manually select layer
– Press trigger (in my case it’s a stream deck button but it could be a customer keyboard shortcut)
Automated steps:
– Press S to show scale property
– Press Command Alt A (select the visible properties)
– Menu: Animation / Add expression (or use the shortcut)
– Use your automation software to paste a pre-defined expression into the expression area, which is now active
– Press numpad enter to exit the expression editor
So with a single button press, I can apply an expression.
Taking it further, you can make it so that you press a button, and a search option pops up, you type a few letters and then press enter to choose your desired expression, and then it gets applied once you select it. You will need to use an advanced automation platform like Soundflow to get that kind of functionality.

In the past there have been some text clipping automation apps on Mac—maybe Windows as well. There were some things that happened with cost and subscriptions and that kind of stuff that made those apps frustrating for me.
At some point, I started building expressions in After Effects and then saving them out as Animation Presets. It takes a little more work on the front end, but, once they are built, I can get to them quickly and even share them with others. I can also easily update them and save over the Preset if I need to.
Thanks for the tips on the automation software!
