If you're on a computer, you can use Mastodon entirely through your keyboard if you prefer.
Press "?" to see a complete list of keyboard commands (on some keyboard layouts press "shift + ?").
Alternatively, you can see the list by clicking on the "Hotkeys" link in the bottom left corner of the screen.
@feditips Driving Mastodon via keyboard, the immediate non-starter is scrolling. I have to leave the home row to use the arrow keys, which is undesirable for a hardcore typist?
