Three tips for people using #Mastodon through a computer:
1. You can stop timelines scrolling automatically by going to Preferences > Slow Mode, tick box and click "Save Changes".
2. There are loads of "hidden" keyboard shortcuts. Press shift + ? (or just ? on some keyboards) to see a complete list of them.
3. There's an optional Tweetdeck-style multicolumn interface called "advanced mode". Go to Preferences > Enable Advanced Web Interface, tick box and click "Save Changes".
