I’ve had this setup for years, finally thought to share. Here are my Text Replacement Keyboard Shortcuts for quickly typing things like ↑✓★⌘ ↓© and fractions.

@smokey And I’ve thought of so many more to add and said to myself, “I’ll add them later.” Then I forget what they are. ¯_(ツ)_/¯

@Mtt It would be nice to be able to add them quickly via Shortcuts when you do think of them, but that doesn’t seem possible :-(
