A very simple and useful reference for the codes that can be used to generate Emojis on popular sites like GitHub or Basecamp.
Emojis are sorted into the categories known from mobile phone keyboards.
Search Emojis by name or view recently selected items to quickly find what you're looking for. Emoji codes are automatically copied to the clipboard on selection.
This is a cross-browser extension. Links for other browsers can be found on the website.
