NotchMindThe shortcut
Press ⌃ ⌘ Space in any text field. The emoji picker opens at the cursor. Type to search, for example “heart” or “rocket”, and press ↩.
The Globe key
On recent Mac keyboards, press 🌐 (or fn). If it does something else, set System Settings → Keyboard → Press 🌐 key to → Show Emoji & Symbols.
Symbols too
Click the expand button at the top right of the picker for the full Character Viewer: arrows, maths, currency, bullets and more. Add favourites so they’re one click away.
Reuse what you’ve used
The picker remembers your recent emoji at the top. For longer text you paste often, like a sign-off or an address, a clipboard history with pins helps; NotchMind, which I make, keeps pinned items one shortcut away. See clipboard history.
