Controls and keybinds · Enthalpy Docs

Enthalpy adds a single key to the controls screen. Everything else is ordinary clicking: use, sneak-use and holding the use button on the right items and blocks. This page lists them all so you can find the one you forgot.

The keybind#

Key	Default	What it does
Open weapon sockets	Shift + right-click	Opens the sockets of the weapon in your main hand: crystal, kit and style on the Kingfish Katana; crystal, muzzle brake and Rail Scales on the Haddock Howitzer.

It is listed under Enthalpy in the controls screen, and you can rebind it to any key or mouse button. It only works with a katana or a howitzer in your main hand, so Shift + right-click does what it always does with anything else in your hand. With the howitzer it opens the sockets instead of powering up a shot, so stand up to fire.

Interactions#

Use is right-click, or your use button. Sneak-use is use while holding sneak.

Machines#

Do this	On this	What happens
Use, empty hand	Any machine or engine	Opens its screen.
Use with a bucket or other fluid container	A machine with a tank	Fills or empties the tank, where that tank allows it. Fuel tanks and water tanks only fill; they never give the fluid back.
Use with the Calibration Tablet or another wrench	A machine or engine	Turns it. See Tools.
Sneak-use with a wrench	A machine, engine or Tank Hatch	Picks it up, keeping its upgrades, energy and settings.
Use with a wrench	A face of a formed Ecotone	Cycles that face's port: Disabled, Input, Output, Input & Output.
Use with a tier kit	A machine that takes kits	Fits the kit. Any kit already there is handed back; the same kit again is refused.
Use with a module	A machine	Drops the module into the first free slot. A message says if there is no room.
Use with a Void Module	The air, or a block that is not a machine	Opens the module's filter: nine slots, a whitelist or blacklist and an Overflow or Always mode.
Click a face in the side panel	A machine's screen	Cycles that face's mode. Right-click cycles back.

Tanks and water#

Do this	On this	What happens
Use with glowstone dust	A formed Tank Hatch or any pane of its glass; a Spawning Basin	Puts the dust in and lights the tank. One dust per tank.
Sneak-use, empty hand	A lit tank or basin	Takes the glowstone dust back out.
Use, empty hand	A Tank Hatch or one of its panes	Opens the hatch's screen.
Use with a water bucket or pipe	A Salt Pan	Fills it with water. It starts boiling when it is full and has heat underneath.
Use, empty hand	A Salt Pan with a finished salt block	Takes the salt block into your inventory.

Weapons and the satchel#

Do this	With this	What happens
Hold use, then release	Haddock Howitzer	Powers up a shot while held and fires on release. Letting go early fires a quick shot; the longer you hold, the harder it hits. Without charge or fish it misfires with a message.
Hold use	A howitzer with Rail Scales	Fires a steady stream of fish for as long as you hold.
Left click, or hold it	A howitzer with a muzzle brake	Fires the brake's ranged attack instead of swinging or mining, repeating while held.
Hold use, then release	Kingfish Katana	Draws the blade, then lunges forward on release. A short tap does nothing; a full draw lunges the furthest.
Use	A katana with an Extendable Blade	Extends the ranged elemental blade at once, in place of the lunge.
Left click	A katana	A normal sword swing.
Use	Tackle Satchel	Opens the satchel.
Right-click the satchel in your inventory while holding fish on your cursor	The satchel	Slips the fish in, up to its capacity. Only ammo fish go in.
Shift-click a crystal, brake, Rail Scales or kit	A weapon's socket screen	Sends it to the socket that matches.

The howitzer, katana and satchel pages say what each of these does in play.

Good to know#

A machine opens its screen only on an empty-handed click, or with an item that does nothing else on it. Holding a wrench, kit or module always does that item's job first.
A formed Ecotone never rotates: a plain click with a wrench sets a port instead.
