Selecting

By default, Blender uses LMB to select items. This can be changed to RMB in the Preferences.

Blender has several selection tools that can be used across the different editors.

Note

Some editors deviate from the keyboard shortcuts shown below. For example, most editors use Shift-LMB to add a single item to the selection, but the Outliner uses Ctrl-LMB. Similarly, most editors use Ctrl-RMB for performing a Lasso Select, but node editors use Ctrl-Alt-LMB.

Most selection tools come in two variants, where one variant is available in the Toolbar and the other in the Select menu. While the variants' names are almost identical (such as Select Box in the Toolbar versus Box Select in the menu), the way they work is a bit different. New users coming from other applications will find the Toolbar variants to be the most familiar.

Toolbar Selection Tools

All the Toolbar selection tools behave the same when clicking an item: they select it (and deselect any previously selected items). If you hold Shift while clicking, the item will be added to the selection (if it's not selected) or removed from the selection (if it is selected).

What makes the tools different is what happens when you drag.

Tweak

Reference

Tool

Toolbar ‣ Tweak

Shortcut

W

Dragging an item will move it around.

Select Box

Reference

Tool

Toolbar ‣ Select Box

Shortcut

W

Dragging will create a rectangle, and select all the items that are partially or completely inside it once you release. (Any other items will be deselected.)

Holding Shift while dragging will add the items to the selection. Holding Ctrl will remove them.

While dragging, you can additionally hold Spacebar to move the rectangle around with the mouse.

Select Circle

Reference

Tool

Toolbar ‣ Select Circle

Shortcut

W

Dragging will select all the items which the circle passed over. Items which you didn't pass over will be deselected.

Holding Shift while dragging will add the items to the selection. Holding Ctrl will remove them.

You can change the radius of the circle in the tool settings (which can be found in the area header, the Tool tab of the Sidebar N, or the Active Tool tab of the Properties editor).

Note

In Object Mode: unlike Select Box, which selects objects as soon as the box covers any part of their geometry, Select Circle only selects objects if the circle passes over their origin point. The origin is shown as an orange dot for selected objects but is invisible for unselected ones, unless "Origins (All)" is enabled in the Viewport Overlays.

This difference in behavior does not apply to the other modes (like Edit Mode and Pose Mode).

Select Lasso

Reference

Tool

Toolbar ‣ Select Lasso

Shortcut

W

Dragging will create a freeform shape, and select all the items inside it once you release. (Any other items will be deselected.)

Holding Shift while dragging will add the items to the selection. Holding Ctrl will remove them.

While dragging, you can additionally hold Spacebar to move the shape around with the mouse.

Note

Select Lasso behaves the same as Select Circle in that it only looks at origin points in Object Mode.

Each of the Toolbar selection tools has a mode to configure how it interacts with existing selections. Note that not every tool supports all of these modes.

Subtract

Removes newly selected items from the existing selection.

Invert Ctrl-I

Intersect

Selects items that intersect with the existing selection.
