Keyboard shortcuts

The full list is also in the app under Settings, Keybinds, where every keyboard shortcut below is rebindable: click an action to capture a new key, with a warning if two actions clash, then Save keybinds. Only the mouse and a couple of held modifiers (Alt to erase, Ctrl + right-click to sample height) are fixed. Your keybinds and slider defaults are saved to their own file, separate from the rest of your settings, so you can hand that one file to another user. Button tooltips in the app always show your own current keys, so they stay correct after you rebind anything.

In the in-game view, W, A, S, D and Q, E drive the fly camera, so the app’s default shortcuts deliberately avoid those keys. The in-game view has its own separate camera keybinds, edited in the same Settings section.

The groups below match the groups in the app’s Keybinds editor. The defaults are:

Views

Key	Action
1	In-game view
2	2D view
3	3D view

Camera

Key	Action
R	Reset view
T	Top-down view, snap the 3D camera straight overhead for a flat map-wide look (R returns to the normal angle)
Space	Hold to orbit the camera (works while a brush panel is open, so you can reposition mid-paint without laying a stroke)

Overlays

Key	Action
G	Cycle grid (off, lines, lines + labels)
F	Slope overlay
Y	Water layer, hide the ocean surface to inspect the seabed
(unbound by default)	Minimap, hide or show the corner map
(unbound by default)	Sun down or up

Map and islands

Key	Action
C	Conjure a new map
N	Add island
H	Reroll salt, roll new inner terrain (and a new world) without moving the coastline
Delete	Delete the selected island(s)
Ctrl + A	Select all islands
Ctrl + G	Flip vertical
Ctrl + H	Flip horizontal

With an island selected, a flip mirrors that island in place, keeping its shape, its paint and any baked channel cuts. With nothing selected it takes the whole map: your painted splats, the biomes and topology, and the islands all mirror together, and the position and rotation sliders keep matching the map you can see. Either way it is instant, and it does not reroll your world.

Brushes

These apply to whichever brush panel is open: the terrain brush, the splat brush, or the biome and topology brushes.

Key	Action
[ or ]	Shrink or grow the brush
O or P	Rotate the brush footprint (5 degrees per press). It turns whichever brush is open, the terrain brush’s stamp included
Tab or Shift + Tab	Next or previous target: the ground texture, the biome, or the topology layer, depending on which brush is open
Alt (held while painting, fixed)	Erase
(unbound by default)	Hardness down or up
(unbound by default)	Spacing down or up
(unbound by default)	Clear layer
(unbound by default)	Cycle falloff: smooth, linear, sharp, soft
(unbound by default)	Cycle stamp shape
(unbound by default)	Cycle symmetry: off, X, Y, quad

Terrain brush

Key	Action
B	Brush mode
(unbound by default)	Strength down or up
Ctrl + right-click (flatten brush, fixed)	Sample height
Ctrl + scroll wheel (fixed)	Brush size, in the 3D view and the in-game view
Alt held (fixed)	Run the brush backwards: raise lowers, bluff softens, pucker digs, ripple inverts

Splat

Key	Action
V	Splat mode (opens or closes the splat panel)
X	Swap to blend, toggles the brush between your current type and the Blend smudge
Alt + right-click (fixed)	Eyedropper, pick the ground texture under the cursor

World layers

Key	Action
J	Biome brush
K	Topology brush
L	Channels, cut water clean across the map
Alt + right-click (fixed)	Eyedropper, pick the biome or a visible topology layer under the cursor

Only one of these docks is open at a time, so picking one closes whichever was up.

Neither brush generates a world for you. On a generated map they edit the derived layers; on a bare map the first stroke starts a blank canvas you paint yourself.

History

Undo and Redo auto-repeat while the key is held. Both pause while a panel is open or a text field is focused, so typing in a box never fires them (your system’s own text undo still works).

Key	Action
Ctrl + Z	Undo
Ctrl + Shift + Z	Redo

Project

Key	Action
Ctrl + N	New project (prompts to save unsaved changes first, then clears to a fresh random island)
Ctrl + S	Save project (re-saves the open project, or opens the Projects panel to name it the first time)
Ctrl + Shift + S	Save project as (opens the Projects panel ready to name a new project)
(unbound by default)	Export now, run the export without opening the panel
(unbound by default)	Save as seed

Panels

Key	Action
4	Custom island panel, draw or import an island shape
5	Open Settings
6	Open Export
7	Open Projects
8	Open Saved Seeds
9	Worldgen panel
I	Island randomizer drawer
Escape	Close the open panel, otherwise deselect everything

Drawing pads

The shape pad and the channel pad take the keyboard while they are open, so none of the shortcuts above fire behind them. A bare letter cannot conjure a new map or flip a view out from under your drawing, and undo belongs to the pad rather than the map.

Shape pad:

Key	Action
1 to 6	Pick a brush: round, coast, blobs, spit, coves, fill
E	Erase, every brush takes land away instead of adding it
[ or ]	Brush size (Ctrl + scroll over the pad does the same)
S	Cycle symmetry: off, X, Y, quad
G	Grid
Space (held)	Pan the pad
Tab	Switch between the Draw tab and the Map preview tab
Ctrl + Z, Ctrl + Shift + Z	Undo and redo your drawing
Enter	New project from this shape
Escape	Close the panel

Channel pad:

Key	Action
[ or ]	Draw width, in metres
Ctrl + Z, Ctrl + Shift + Z	Undo and redo a stroke
Enter	Apply
Escape	Cancel

Sliders

Input	Action
Click or drag	Set value
Ctrl + drag	Fine, one step per pixel
Tab	Focus the slider (enables arrow keys)
Arrow keys	Step by one
Ctrl or Shift + arrow	Step by ten
Home or End	Minimum or maximum
Double-click slider	Reset to default
Double-click value	Type a value

Mouse on the canvas

Input	Action
Double-click (2D or 3D)	Select island
Ctrl or Shift + click an island	Add or remove it from the selection (select several at once)
Ctrl + A	Select all islands
Click water	Deselect all
Drag a selected island	Move it (moves the whole selection together; painted textures follow)
Drag (3D)	Orbit the camera
Scroll (3D)	Zoom
Drag (2D minimap)	Pan
Scroll (2D minimap)	Zoom
