The basics

You can move around with the WASD keys. If you press e (right hand) or q (left hand), you'll interact with whatever's in front of you, or if you press r (right hand), you'll interact with what you're standing on. You can use the arrow keys to change the direction you're facing. The number keys will select an item in your hotbar, or you can click on an item in your hotbar to select it.

Tools

Some tools (such as hammers and fluid guns) are used by having them selected in your hotbar and then clicking on the world, while others (such as pickaxes and shovels) need to be equipped and then used with an interaction key (e, q or r as described above). To equip an item, you can drag it to the L or R slot to the right of the hotbar, or you can press { with it active in the hotbar to equip it in your left hand or } to equip it in your right hand.

More hotkeys

Pressing shift+f will toggle autofocus, i.e. whether the camera will follow the player's movements. Pressing f by itself will reset the camera to the default zoom level and (if autofocus is off) center on the player.

Entity interactions

Interacting with animals and ships will cause you to ride them, unless you have a weapon equipped, in which case interacting with an animal will attack it. To dismount an animal or ship, press r. To enter a ship's realm, interact with the ship while holding ctrl. To destroy a ship and its realm (this is dangerous and cannot be undone!), hold ctrl+alt and interact with the ship.
