If you're using Mastodon through the web on a computer, you might like to know:

- You can type emoji by typing a colon : and then keywords. For example :sun will bring up emoji with the word "sun". Alternatively use the picker 😂

- There are many keyboard commands, press shift + ? (or just ? depending on your keyboard layout) to see all the hotkeys.

- There's an optional multicolumn web interface. Activate it at Preferences > Enable Advanced Web Interface, tick box and click "save changes".
