Emoji and emoticons

list of emoticons  are a spin on common emoticons, which you can use to enhance your Slack messages.

Adding emoji to your Slack messages
There are two ways you can use emoji in your messages:
  • Type the emoji code
  • Select from the emoji menu

Type the emoji code
Slack uses the standard emoji codes found at Emoji Cheat Sheet. You can quickly add emoji to your messages by typing in the code.

If you’re not sure of the emoji code, just type : followed by the first few letters, and an autocomplete menu will appear. Click the emoji you want to use, or on desktop, press Tab to cycle through the list.

Select from the emoji menu
Desktop
     
Windows Phone
  1. Click the   light gray smiley face in the message box to open the emoji menu.
  2. Tab through the icons at the top to browse groups of emoji, or start typing a word to search the   emoji codes.
  3. Click your chosen emoji. It'll be added to your message.
Tip: You can add your own easy-to-remember codes for emoji in Slack. Simply:
  1. Go to the Customize page.

  3. Choose an emoji from the drop-down menu.
  4. Under Choose a name, enter the new code you'd like to use.

Choosing your default skin tone
On desktop, you can set your emoji skin tone preference by clicking the ✋ hand icon in the bottom right corner of the emoji menu. Pick a default skin tone, or switch it up on the fly.

By default, if your message or comment contains only emoji, they'll appear larger on both mobile and desktop. In the case of desktop, this is provided you're using the Clean  message theme.

  2. Choose Preferences.
  3. Select the Messages & Media tab.
