Keybind Reference

Keybind Reference

Every keyboard and mouse binding in the desktop Tile Editor. Press ? or F1 in the editor to see the same table in-app (help page 9).

Bindings are contextual — several keys do different things depending on whether edit mode is on. Those are marked.

Cheat Sheet

The dozen you will actually use every session:

Key	Action
E	Toggle edit mode (terrain painting)
F	Fit all tiles in view
Ctrl+S	Save
Ctrl+Z	Undo
Ctrl+click	Create node at cursor
RMB drag	Pan the map
Scroll	Zoom
[ ]	Brush smaller / larger
- =	Brush weaker / stronger
T	Toggle track overlay
Esc	Cancel anything / close panel
? / F1	Help

Display Modes

Key	Action
H	Heightmap mode — elevation contours
V	Vegetation mode — veg/biome layer
W	Water mode — water coverage
S	Toggle hillshade
D	Toggle diff overlay (modified tiles)
O	Toggle OSM overlay
T	Toggle track display
N	Toggle node dots
I	Toggle tile info tooltip

View And Navigation

Key	Action
F	Fit view to tiles
R	Redraw / refresh
Ctrl+R	Reload graph and mod data from disk
Scroll	Zoom in / out
RMB drag	Pan the map
MMB	Pan (middle mouse)
Mousewheel over panel	Scroll lists
← → Tab	Navigate help pages

Note: help page 2 lists LMB drag for panning while the keybind summary lists RMB drag. Right mouse is the reliable pan outside edit mode; in edit mode LMB paints, so use RMB or MMB there.

Interface Scale

Key	Action
Ctrl+-	Shrink UI scale
Ctrl+=	Grow UI scale
Ctrl+0	Reset UI scale to 100%

Scale persists between launches. The sidebar A- / 100% / A+ controls under Workspace do the same thing.

Files

Key	Action
Ctrl+S	Save modified tiles / mod project
Ctrl+Z	Undo — terrain strokes or mod edits (up to 50 mod steps)
L	Load track graph JSON
B	Pick game / bridge folder (outside edit mode)
Drag-drop folder	Drop a tile folder on the window to load it
Esc / Q	Quit, cancel, or close

Terrain Editing

Edit mode only — press E first. LMB paints, RMB erases.

Key	Action
E	Toggle edit mode
B	Cycle brush type (edit mode)
[ / ]	Brush size down / up
Ctrl+Scroll	Brush size
- / =	Brush strength down / up
LMB	Paint / raise
RMB	Erase / lower
MMB	Eyedropper — sample height or veg at cursor
0–7	Vegetation preset (veg mode)
,	Set height floor clamp to cursor height
.	Set height ceiling clamp to cursor height
Ctrl+,	Clear floor clamp
Ctrl+.	Clear ceiling clamp
Ctrl+X	Export heightmap as PNG

Brush Types

Cycle with B in edit mode.

Brush	Effect
Raise	Raise (LMB) or lower (RMB)
Flatten	Level to the height you first clicked
Paint	Stamp an exact target height
Smooth	Average pixels with neighbours
Noise	Add fBm procedural noise
Erode	Simulate hydraulic erosion

Terrain Selection

Press M in edit mode.

Key	Action
M	Toggle selection mode
Click+drag	Rect / lasso select
Click (wand)	Flood-fill select similar values
Ctrl+C	Copy selection
Ctrl+V	Paste selection — click to place
Ctrl+X	Cut selection / export PNG
Delete	Clear selected region

Track Editing

Input	Action
LMB	Select node or segment
Click segment	Selects anywhere along the line, not just the midpoint
Click empty space	Deselect
Click selected node	Second click starts drag
Drag release	Commit move — samples terrain height
Ctrl+click map	Create node at cursor
Ctrl+click node	Finish a connection to that node
Delete	Delete selected node or segment
Esc	Cancel drag / connect / place
Ctrl+drag	Rubber-band select nodes
Shift+drag	Add to group selection

Connection Feedback Colours

Drag a node toward a target and watch the highlight — it tells you what will happen on release:

Highlight	Result
Snap ring on a node	Connect the two with a segment
Cyan on a segment	Insert the node into that segment (splits it in two)
Yellow on a segment (Shift+drag)	Insert the node and add a turnout diverge leg

Inserting into a segment deletes the original and creates two; the new node inherits a bezier heading. The yellow turnout variant uses the current Geo → Turnout settings for angle and length.

Tile Generation Panel

Input	Action
Click tile cell	Queue a tile for generation
Drag cells	Box-select a region to queue
RMB tile cell	Remove from queue
Scroll	Zoom the generate grid
MMB drag	Pan the generate grid
Run	Generate all queued tiles

Contextual Keys

Three keys change meaning with edit mode, which is the most common source of confusion:

Key	Outside edit mode	In edit mode
B	Pick game / bridge folder	Cycle brush type
LMB	Select / pan	Paint
RMB	Pan	Erase

M, [, ], -, =, ,, ., and 0–7 only do anything in edit mode.

Status Bar

The bottom bar reports the current action and errors. ↩ N shows how many mod undo steps are available.

In-Game F9 Workspace

Most F9 authoring actions are labelled buttons rather than hidden hotkeys. The global/contextual inputs are:

Input	Action
F9	Open or close the in-game Tile Editor
Esc	Cancel pointer placement, terrain stroke, or the active in-game action
[ / ]	Decrease / increase the in-game terrain brush radius
Alt + pointer/camera input	Temporarily give the game camera priority while editing
Shift+/	Show the in-game survey/measurement HUD
World click while a placement button is armed	Place/select the requested node, object, town, loader, or signal

Signals and Operations deliberately expose save, refresh, snap, lock, undo, and redo controls in their panels so authors do not have to memorize another set of single-letter bindings.
