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 of an object – Press the RMB.
Moving the cursor position – Press the LMB.
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.
These buttons perform an operation when clicked with LMB.
The color button stores a color value shown in its background. LMB buttons open the Color Picker.
Radio buttons are used to choose from a small selection of “mutually exclusive” options.
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:
- In/Decremental Steps
To change the value in steps, click LMB on the small triangles (number button only).
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.
- 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:
- Press Return or LMB outside the field to apply the change.
- Press Esc or RMB will cancel the value.
- Press Tab to jump to the next number button or Ctrl-Tab for the previous.
- Press Minus while hovering over the button to negate the value.
