Blender 3D: Noob to Pro/Non-standard equipment

This module is applicable only to users with non-standard input devices. If you have both:

  • a three-button mouse

and

  • a keyboard with a numpad,

then you can skip this module.

Keyboards lacking a numpad[edit]

Most modern laptops have a pseudo-numpad, a set of keys in the main keypad which double as a numpad. The keys typically used for this purpose are:

 7key   8key   9key   0key 
 U   I   O   P 
 J   K   L   ; 
 M   ,Key   .Key   SLASH 

When used as a pseudo-numpad, these keys typically act as the following keys from a true numpad:

 Num7   Num8   Num9   Num/ 
 Num4   Num5   Num6   Num* 
 Num1   Num2   Num3   NUM− 
 Num0   NumENTER   Num.   Num+ 

The numpad functions of these keys can often be toggled with  F11  or  NUMLOCK  on PCs or with  F6  on Macs. Alternatively, you can often temporarily activate the numpad behavior by holding down  Fn .

If your keyboard has the alternate labellings but you don't know how they work, consult your laptop's owner manual.

As a last resort, you can use the "Emulate Numpad" feature of Blender. This will allow you to use the normal numeric keys as if they were numpad numerics. Instructions for enabling this feature may be found in the "User Preferences Windows" module.

Blender uses the numeric keypad quite a bit. If you envision using your laptop for this kind of work, it may be worth investing in a USB Numeric Keypad. On eBay, prices for simple external numpads start around $10 USD.

Non three-button mice[edit]

For single-button mouse users, make sure that View & Controls (Input for Blender 2.54) (under "User Preferences" on the left-most drop-down menu) → Emulate 3 Button Mouse is enabled.

On many computers with two-button mice,  MMB  can be emulated by simultaneously clicking  LMB  and  RMB . On Windows machines you'll need to set this up in the mouse settings in your Control Panel. On a Mac, open the Keyboard and Mouse preference pane and enable Use two fingers to scroll. Alternatively, by selecting Emulate 3 Button Mouse under User Preferences,  MMB  can be emulated by simultaneously clicking  Alt  and  LMB .

Recent IBM Thinkpad laptops allow you to disable the 'UltraNav' features of the middle mouse button in order to use it as a 'normal' third button. Alternatively, some laptops allow areas (called gestures) on the movement pad to act as  MMB  or  RMB , and these can be set up in the Control Panel in the Mouse Pointer options, selecting gestures and editing features there.

Apple single-button mouse[edit]

Apple single-button mouse substitutions
Notation Single-button Substitute Description
 LMB   MB  the Mouse Button
 RMB   Cmd + MB  Apple key + the Mouse Button
 MMB   Alt + MB  Option (Alt) key + the Mouse Button

While Mac OS X natively uses both the  Ctrl + MB  and  Cmd + MB  to emulate  RMB , recent Blender releases for Mac OS X use only  Cmd + MB  for this purpose. This behavior is documented in the OSX Tips file that comes with the Mac version. You can also set in System Preferences for the mouse to sense a right-click.

Note also that in the new, "unibody" design, the mouse button is under the trackpad, and the shortcut for  RMB  is clicking with two fingers simultaneously, which can be enabled in the System Preferences.

Laptops lacking a middle button but with a smart-pad[edit]

Many laptops have smart pads. Smart-pads can use gestures to give the effect of  MMB . The default for an Elan® Smart-Pad is two-finger tapping equivalent to clicking a  MMB . Dragging two fingers is the same as turning a mouse wheel.

Tablet PCs[edit]

To get the effect of  MMB  in a viewport, drag your pen around while holding down the  Alt  key.
