For the purposes of this document, you should assume the following abbreviations:

Control	Abbreviation
Left Mouse Button	LMB
Right Mouse Button	RMB
Middle Mouse Button	MMB

Standard

These controls represent the default behavior when clicking and dragging in the viewports with no other keys or buttons pressed. These are also the only controls that can be used to navigate the orthographic viewports.

Control	Action
Perspective
LMB + Drag	Moves the camera forward and backward and rotates left and right.
RMB + Drag	Rotates the viewport camera.
LMB + RMB + Drag	Moves up and down.
Orthographic (Top, Front, Side)
LMB + Drag	Creates a marquee selection box.
RMB + Drag	Pans the viewport camera.
LMB + RMB + Drag	Zooms the viewport camera in and out.
Focusing
F	Focuses the camera on the selected object. This is essential to make the most out of tumbling the camera.

Magic Mouse and Magic Trackpad

On a Mac, after enabling Secondary click in System Preference -> Mouse for the Magic Mouse, or enabling Secondary click with two fingers in System Preference -> Trackpad for the Magic Trackpad, the following controls are available.

Magic Mouse	Magic Trackpad	Action
Persepctive
LMB + Drag	1 Finger Click + Drag	Moves the camera forward and backward and rotates left and right.
RMB + Drag	2 Finger Click + Drag	Rotates the viewport camera.
1 Finger Touch + Drag	2 Finger Touch + Drag	Rotates the viewport camera.
Orthographic (Top, Front, Side)
LMB + Drag	1 Finger Click + Drag	Creates a marquee selection box.
RMB + Drag	2 Finger Click + Drag	Pans the viewport camera.
1 Finger Touch + Drag	2 Finger Touch + Drag	Pans the viewport camera.
Focusing
F	F	Focuses the camera on the selected object. This is essential to make the most out of tumbling the camera.

Game-style

The WASD controls will feel natural to those who are used to playing shooter games on the PC. They are enabled by default and can be used whenever you are holding RMB. This means you will still use RMB to turn the camera while navigating in this way.

These controls are mirrored on the arrow keys and num pad to provide alternate access to them.

All of these controls are only valid in a Perspective viewport, and by default you must hold RMB to use the WASD game-style controls.

Control	Action
W \| Numpad8 \| Up	Moves the camera forward.
S \| Numpad2 \| Down	Moves the camera backward.
A \| Numpad4 \| Left	Moves the camera left.
D \| Numpad6 \| Right	Moves the camera right.
E \| Numpad9 \| Page Up	Moves the camera up.
Q \| Numpad7 \| Page Dn	Moves the camera down.
Z \| Numpad1	Zooms the camera out (raises FOV).
C \| Numpad3	Zooms the camera in (lowers FOV).

When zooming the camera, holding the RMB will hold the FOV, preventing it from snapping back to its default settings. The FOV will remain until the RMB is released.

When navigating with WASD while holding down the RMB, you can rotate the mouse wheel up to speed up your movement, or rotate the mouse wheel down to slow down your movement.

While using the Magic Mouse or Magic Track you will not be able to change the speed of the camera by using the RMB + Mouse Scroll Wheel, you will need to adjust it using the Viewport camera speed option.

Pan, Orbit, and Zoom

Unreal Editor supports Maya-style pan, orbit, and zoom viewport controls, making it much easier for Maya artists to jump into the tool. If you are unfamiliar, here is a breakdown of the keys:

Command	Description
Alt + LMB + Drag	Tumbles the viewport around a single pivot or point of interest.
Alt + RMB + Drag	Dollies (zooms) the camera toward and away from a single pivot or point of interest.
Alt + MMB + Drag	Tracks the camera left, right, up, and down in the direction of mouse movement.

The use of the F key is not limited to Maya-style controls. You can always press F to focus on a selected object or group of objects!

Selection Controls

You can select Actors in the viewport individually simply by clicking on them or in groups using a box selection in the 2D viewports:

Control	Action
Simple Selection
LMB	Selects the Actor under the cursor, replacing the current selection.
Ctrl + LMB	Adds the Actor under the cursor to the current selection.
Box Selection (2D Viewports Only)
LMB + Drag	Replaces the current selection with the Actors contained in the box.
Shift + LMB + Drag	Adds the Actors contained in the box to the current selection.
Ctrl + RMB + Drag	Removes any select Actors in the box from the current selection.

Transform Controls

These controls relate to moving, rotating, and scaling Actors in the viewports using the transform tools:

You can see which tool is active in the viewport toolbar:

Control	Action
LMB + Drag (on Transform Tool)	Moves, rotates, or scales the currently selected Actors, depending on the active transform gizmo.
W	Selects the Move Tool.
E	Selects the Rotate Tool.
R	Selects the Scale Tool.
V	Toggles vertex snapping which allows you to snap to the vertices of other geometry in the world.
MMB + Drag (on Pivot)	Moves the pivot of the selection temporarily to offset transformations.
Move Tool Controls (Perspective Viewports Only)
Ctrl + LMB + Drag	Moves the currently selected Actor(s) along the X axis.
Ctrl + RMB + Drag	Moves the currently selected Actor(s) along the Y axis.
Ctrl + LMB + RMB + Drag	Moves the currently selected Actor(s) along the Z axis.
Move Tool Controls (Orthographic Viewports Only)
Ctrl + LMB + Drag	Moves the currently selected Actor(s) along the plane defined by the two visible axes.
Rotate Tool Controls (Perspective Viewports Only)
Ctrl + LMB + Drag	Rotates the currently selected Actor(s) along the X axis.
Ctrl + RMB + Drag	Rotates the currently selected Actor(s) along the Y axis.
Ctrl + LMB + RMB + Drag	Rotates the currently selected Actor(s) along the Z axis.
Scale Tool Controls
Ctrl + LMB + Drag	Scales the currently selected Actor(s) uniformly along all axes.
Move/Scale Tool Controls (Orthographic Viewports Only)

Display Controls

These controls affect how the level is displayed in the viewport.

Control	Action

Ctrl + R	Toggles real-time playback in the active viewport.
F11	Toggles immersive mode, which puts the viewport into full-screen.
