Emulate 3 Button Mouse

• RMB - Right Mouse Button

• MMB - Middle Mouse Button

• LMB - Left Mouse Button

Blender can be configured to work with pointing devices which do not have an MMB (such as a two-button mouse, Apple’s single-button mouse, or laptop touch-pad). The functionality of the three mouse buttons will then be emulated with key/mouse button combinations as shown in the table below.

Shortcuts for supported mouse hardware

3-button Mouse	2-button Mouse	Apple Mouse
LMB	LMB	LMB (mouse button)
MMB	Alt-LMB	Alt-LMB (Option/Alt key + mouse button)
RMB	RMB	Cmd-LMB (Command/Apple key + mouse button)

Mouse/Keyboard combinations referenced in this manual can be expressed with the combinations shown in the table. For example:

• MMB drag becomes Alt-LMB drag.
• Shift-Alt-RMB becomes Shift-Alt-Cmd-LMB on a single-button mouse.

Selection

Selection of an object – Press the RMB.
Moving the cursor position – Press the LMB.

View Manipulation

Orbit - Rotate the 3D View by holding the MMB.
Move - Move the 3D View by holding Shift-Alt-RMB buttons and dragging the object.
Zoom Style - Zoom in and out by scrolling MMB.

Buttons

• Operation Buttons

These are buttons that perform an operation when clicked with LMB.

• Color Buttons

The color button stores a color value shown in its background. LMB buttons open the Color Picker.

• Radio Buttons

Radio buttons are used to choose from a small selection of “mutually exclusive” options.

• Number Buttons

Number buttons hold numeric values.

Number buttons can be identified by the triangles pointing left (◂) and right (▸) on the sides of the button. The second type number sliders have a bar in the background and are used for values in a range, e.g. percentage values. Both types have round corners. In most cases, they contain a name and a colon followed by the number. The value can be edited in several ways:

1. In/Decremental Steps
   To change the value in steps, click LMB on the small triangles (number button only).

2. Dragging
   To change the value in a wider range, hold down LMB and drag the mouse to the left or right. Hold Ctrl to snap to the discrete steps while dragging or Shift for precision input.

3. Text Input
   Press LMB or Return to edit the value as a text field.
   When entering values by hand, this button works like any other text field:

   1. Press Return or LMB outside the field to apply the change.

   2. Press Esc or RMB will cancel the value.

   3. Press Tab to jump to the next number button or Ctrl-Tab for the previous.

   4. Press Minus while hovering over the button to negate the value.
