Selecting

By default Blender uses the LMB to select items in the Blender window. Alternatively, the RMB can be used instead by changing the Preferences. Blender has several selecting tools that can be used across the different editors.

Selection Tools

Select Regular

Hotkey

LMB

Clicking on an item selects it, using modifier keys you can perform other operations.

Select Box

Reference

Menu

Select ‣ Box Select

Hotkey

B

To activate the tool, press B or click and drag LMB. With Select Box you draw a rectangle while holding down LMB. Any item that lies even partially within this rectangle becomes selected. If any item that was last active appears in the selection it will become active.

For deselecting items, use MMB, or Shift-LMB.

C

Circle Select C allows you to select multiple items within a circular area. Move your mouse over any items within the circular area (shown with a dotted circle) while holding LMB to select those items. Alternatively, use MMB to deselect them. When you’re done selecting, press RMB or Esc. To change the diameter of the circle, scroll with the Wheel or use the NumpadPlus and NumpadMinus keys.

Select Lasso

Reference

Hotkey

Ctrl-RMB

Lasso Select is used to create a free-form selection. Simply hold Ctrl-RMB while drawing a dotted line around the items you want to select. The shape you draw will be automatically closed by connecting a line from the current position back to the starting point.

Lasso Select adds to the previous selection. For deselection, use Shift-Ctrl-RMB.
