You’re definitely right. That’s funny. When I pasted it , it was totally a backslash. The cow must have switched it out.

Also, for some reason using the hotkey inside of Process Palette gives some kind of error in AE about trying to run the script 2x. To get around it you have to set up the hotkey in the Atom keymap.

I actually got this info from this tutorial series. https://www.fxphd.com/details/539/
It’s behind a paywall, but you can just sign up for a month, get access to all of their tutorials, and then cancel. REALLY helpful.

There’s actually a very useful package for this called Process-Palette (by morassman) that let’s you run shell commands directly from Atom. And you can run Extendscripts directly from there. Same as hitting the play button in Exendscript.

Go to Atom>Preferences and in Settings choose Install

Search for Process-Palette under Packages and click Install

Now from the menu choose Packages > Process Palette > Edit Configuration > Global Configuration

Click Add to add a new command

Give it whatever Namespace and Action Name you want.

Under Shell Command if you’re on a Mac enter:
osascript -e 'tell application "Adobe After Effects CC 2018" to activate' -e 'tell application "Adobe After Effects CC 2018" to DoScriptFile "{fileAbsPath}"'

Windows enter:
"C:\Program Files\Adobe\Adobe After Effects CC 2018\Support Files \afterfx.exe" -r {fileAbsPath}

Under Keystroke give it a hotkey that’s not used anywhere else in Atom.

Scroll down to Notifications, and you’ll probably want to turn off both Success & Error

While you’re at it another package you may want to install is: React.js (by orktes), it makes it so Atom recognizes .jsx files for the auto-color functionality.
