Quick tip for fellow Slack power users: macOS 27 has a hidden command for Slack-style inline Emoji search.
A dropdown with Emoji suggestions appears when you type colon (:) and a keyword.
Enable the feature in the Terminal:
• The feature is quite reliable in AppKit text editors such as TextEdit, Notes, and Calendar.
• It works in Catalyst apps like Messages and Books, but there’s a refresh bug. Press an arrow key after typing a few letters to make suggestions appear.
• It doesn’t have a WebKit implementation, so this new command will not work when drafting emails or reminders. Emoji suggestions appear in search fields.
Restore to defaults with:
sudo defaults delete /Library/Preferences/FeatureFlags/Domain/Stickers InlineEmojiSearch
