Emote is a modern emoji picker for Linux 🚀.
Written in GTK3, Emote is lightweight and stays out of your way.
Launch the emoji picker with the configurable keyboard shortcut
Ctrl+Alt+E and select one or more emojis to paste them into the currently focussed app.
Note - Emote under Wayland cannot automatically paste the emoji into other apps and also requires manual registering of a global keyboard shortcut - Hotkey In Wayland. This is due to intentional restrictions in the design of Wayland itself.
