On the Mac OS I have many keyboard shortcuts set up to type strange characters, such as "\pi" types a PI symbol (π), or even emojis. There is a system pref. pane, next to the "autocorrect" panel, where you type in the "\pi" and then I copy/paste the appropriate symbol from the Character viewer.

How can I enable similar functionality in Windows?
I seem to remember colleagues memorizing numerical Alt-Codes (eg. Alt+1234 to type some symbol). Is there a simple replace-as-you-type or "autocorrect" as you type feature that can be enabled system-wide, to insert greek characters and arrows etc.? (I know MS Office apps have their own, isolated, autocorrect features, but I want system wide shortcuts – eg. for notes, email, word etc.).
I found this answer: Text shortcuts for faster communication
The solution, AutoHotKey requires Basic programming and I'm hoping for less overhead. If there is no simpler solution, then I'll go with AutoHotKey (some day when I decide it's worth the time to figure it out).
Looking for solution on Windows 10 Pro.
