⏩ Emoji Shortcodes
Emoji Shortcodes are codes used on various websites to speed up emoji insertion using a keyboard. These begin with a colon and include a shorter version of an emoji name. For example :joy: shows 😂 Face With Tears of Joy on most platforms that support shortcodes.
These codes vary slightly from platform to platform. Two major uses of these codes are on Github or Slack. Facebook has also used its own version of emoji shortcodes in the past.
