======Tree Window navigation======

The [[tooltree_window|Tree Window]] has multiple controls and navigation modes to help you move around efficiently. 

Navigate using Standard, Trackball, or Traveler mode or use the [[tree-window-navigation#universal zoom and focus controls|universal zoom and focus controls]] that work in any mode. You can also navigate using alternative control schemes. 

For camera controls and other keyboard shortcuts, see [[hotkeys|Hotkeys]].

=====Navigation modes=====

There are three modes of navigation: Standard, Trackball, and Traveler. To switch between modes, right-click in the Tree Window and select **Window** > **Navigation**.

====Standard mode (Default)====
Standard mode lets you manipulate the scene like it’s surrounded by an imaginary trackball whose up vector is always aligned with the global z-axis. This navigation mode uses a pivot point to control where the camera’s looking and to define the point of rotation.

^**Action**^**Three-button mouse**^**Two-button mouse**^**One-button mouse or touchpad**^
|**Pan**|Middle-click and drag in any direction.|Hold Alt (macOS: hold Option) and click and drag in any direction.||
|**Rotate**|Click and drag left and right or up and down.|||
|**Zoom**|Rotate the mouse wheel or hold the left and middle buttons and drag up or down. \\ To zoom and push the pivot point: Hold Shift and the left and middle buttons and drag up or down.|Hold Alt+Shift (macOS: hold Option+Shift) and click and drag up or down.|Swipe up or down or hold Alt+Shift (macOS: hold Option+Shift) and click and drag up or down.|

====Trackball mode====
Trackball mode lets you manipulate the scene as though it were surrounded by an imaginary trackball, without an up vector restriction. This navigation mode uses a pivot point to control where the camera’s looking and to define the point of rotation.

^**Action**^**Three-button mouse**^**Two-button mouse**^**One-button mouse or touchpad**^
|**Pan**|Middle-click and drag in any direction.|Hold Alt (macOS: hold Option) and click and drag in any direction.||

====Traveler mode====
Traveler mode lets you navigate a scene as though you’re a participant in it. Unlike the other modes, there is no pivot point. Instead, mouse motions are mapped to actions that move an imaginary traveler through the scene. 

^**Action**^**Three-button mouse**^**Two-button mouse**^**One-button mouse or touchpad**^
|**Walk**|To keep a static viewpoint along the xy-axis, click and drag. Drag slower or faster to adjust the walking speed. \\ To move to where the traveler is looking, hold Shift and click and drag.|||
