Master Keyboard Shortcuts Reference¶

This page provides a comprehensive compendium of all keyboard shortcuts, modifier keys, and mouse actions implemented in nEditor, collected from all modules and tabs across the application.

1. Global System Shortcuts and History¶

Shortcuts available globally while working in the 3D scene:

Shortcut	Function	Description
`Ctrl`+`Z`	Undo	Reverts the last modification performed in the scene (undo history stores up to 50 steps).
`Ctrl`+`Y`	Redo	Reapplies the previously undone action.
`Esc`	Cancel / Deselect	Aborts the active tool, exits edit mode, or deselects active selections.

2. Camera Controls and View Modes¶

Detailed camera documentation is available on the Camera Controls page.

Global Camera Modes:¶

Key	Feature	Description
`F2`	Isometric View (2D)	Toggles the camera between perspective and orthographic top-down view (90°).
`F3`	Rotate 2D View by 15°	Rotates the 2D top-down view by 15° around the vertical axis. Automatically enters 2D mode from perspective.
`F5`	Precision Mode	Lowers rotation, pan, and zoom sensitivity (10–15×), facilitating micro-adjustments.

Control Style: Blender Way (Default):¶

Action	Controls	Function
Orbit (Rotate)	Middle Mouse Button (MMB)	Hold the mouse wheel and drag to orbit around the central focus point.
Pan (Move View)	`Shift` + MMB	Hold Shift with the mouse wheel and move the mouse to pan parallel to the screen.
Zoom In / Out	Mouse Scroll Wheel	Scroll forward or backward. Below 30 m above ground, speed slows down 4× automatically.

Control Style: OMSI Way (Classic):¶

Action	Controls	Function
Relocate Focus Point	Right Mouse Button (RMB)	A single click on the terrain triggers a smooth camera glide (Smooth Move).
Zoom In / Out	Hold RMB + Vertical Drag	Hold the right mouse button and drag forward or backward.
Orbit Around Pivot	Middle Mouse Button (MMB)	Hold the mouse wheel and move the cursor to rotate around the focus point.

3. Terrain Topology and Painting¶

Detailed guides are available in Terrain Topology and Terrain Paint.

Shortcut	Context / Tool	Action
`Z`	Vertical node elevation adjustment maintaining a straight linear slope.
`X`	Vertical height adjustment with a dual smooth S-curve (flat tangents at both ends).
`C`	Vertical height adjustment with a sag curve (Ease-in, flat base tangent, steep exit).
`V`	Vertical height adjustment with a crest curve (Ease-out, steep base start, flat crest tangent).
`Ctrl` (during `Z`)	Steps height in discrete 0.1 m increments.
`Shift` + LMB	Selects two or more nodes.
`Del`	Deletes the selected node or spline segment.
LMB / `Enter`	Confirms the node position.
RMB / `Esc`	Cancels moving or spline creation.

Fragments Mode (FRAGMENTS):¶

Shortcut	Function
`G`	Translates the entire selected spline segment horizontally.
`Z`	Adjusts elevation of the entire segment vertically.
`R`	Rotates the entire segment around its axis.
`Ctrl`+`C` / `Ctrl`+`V`	Copies and pastes the spline segment.
`Del`	Deletes the selected spline fragment.
`Shift` + LMB / Box	Selects multiple segments simultaneously.
`Ctrl` + LMB / Box	Deselects segments from the active selection.

7. Custom Shapes¶

Detailed guide is available in Custom Shapes.

Drawing and Edge Generation:¶

Shortcut	Mode	Function
LMB	DRAW SHAPE	Places consecutive polygon outline vertices.
`Enter` / `F` (or click near start)	DRAW SHAPE	Closes the polygon boundary and generates the 3D mesh.
`F`	CREATE SHAPE FROM EDGES	Generates a triangle mesh bridging selected spline or shape edges.
`E`	CREATE SHAPE FROM EDGES	Initiates edge extrusion (extruding new geometry faces from selected edges).
`Esc`	DRAW / EDGES	Cancels drawing/creation mode and returns to face editing.

Mesh Editing (Vertices / Edges / Faces / Whole Mesh):¶

Shortcut	Selection Mode	Function
`G`	All modes	Translates selected sub-elements horizontally.
`Z`	All modes	Adjusts vertical elevation (creating ramps, steps, and slopes).
`R`	All modes	Rotates selected sub-elements.
`S`	Whole Mesh	Scales the entire 3D mesh volume proportionally.
`E`	Edges	Extrudes selected edges into new polygons.
`Left` / `Right` / `Up` / `Down`	Faces / Whole Mesh	Shifts texture coordinates (UV Offset) across faces.
`Del`	All modes	Deletes selected vertices, edges, faces, or the whole mesh.
`Shift` + LMB / Box	All modes	Adds sub-elements to the current selection.
`Ctrl` + LMB / Box	All modes	Removes sub-elements from the current selection.
LMB / `Enter` / `Space`	During transform	Confirms geometry transformation.
RMB / `Esc`	During transform	Cancels operation and restores previous geometry.

8. Crossings and Traffic Signals (Crossing Editor)¶

Detailed guide is available in Crossings.

Creating Crossings from Splines:¶

Shortcut	Function
`Shift` + LMB / Box	Adds splines to selection prior to generating the crossing.
`Ctrl` + LMB / Box	Removes splines from selection.

Editing Crossing Paths and Nodes:¶

Shortcut	Context	Function
`N`	Selected node	Begins extending a new traffic path from the selected node.
`N`	No node selected	Places the start of a new path within the intersection footprint.
`R`	During path creation	Toggles path segment geometry between straight (STRAIGHT) and curved (CURVE).
`G`	Selected dynamic node	Translates node horizontally with automatic snapping to neighboring paths and splines.
`Alt`	During translation (`G`)	Constrains node movement along its original tangent axis (prevents angle kinks).
`Alt`	Selected node (resting)	Re-aligns path heading tangentially to the preceding segment.
`Z`	Selected dynamic node	Adjusts node vertical height using mouse dragging.
`Ctrl`	During height adjustment (`Z`)	Snaps elevation in discrete 0.1 m increments.
`Shift` + LMB	Two selected nodes	Selects start and end nodes for the COMPLETE TO operation.
`Del`	Selected path	Deletes the specified path from the intersection.
LMB / `Enter`	During transform	Confirms the new node position.
RMB / `Esc`	During transform	Cancels node translation and restores previous coordinates.

9. Universal Selection and Confirmation Rules¶

All 3D manipulation tools in nEditor share a standardized interaction model:

Action	Function
LMB (Single click)	Selects a single element (deselecting others).
LMB Drag (Box Select)	Selects all elements within the bounding rectangle.
`Shift` + LMB / Box	Multiselect – adds targeted elements to the active selection.
`Ctrl` + LMB / Box	Deselect – removes targeted elements from the active selection.
LMB / `Enter` / `Space`	Confirm – confirms the active translation, rotation, scaling, or extrusion.
RMB / `Esc`	Cancel – immediately aborts the action and restores pre-edit state.
