The ui command sets generic tool-interface preferences and adjusts mouse-button assignments for interactive manipulation.• ui autostart true | false tool-name
• ui dockable true | false tool-name
Whether the tool should start automatically upon subsequent ChimeraX startup; saved in preferences. Can also be adjusted through context menus.
• mousemode [ control ] [ alt ] [ command ] [ shift ] [ leftMode function ] [ middleMode function ] [ rightMode function ] [ wheelMode function ] [ pauseMode function ]
Whether panels of the tool should be allowed to reinsert automatically when dragged over the main window, as opposed to remaining separate; initially true for all panels except the Help Viewer; saved in preferences. Can also be adjusted through context menus.
The mousemode command (same as ui mousemode) assigns ChimeraX functions to the left, middle, and right mouse buttons, alone and in combination with the modifier keys control, alt, command, and shift. In addition, wheelMode refers to scrolling and pauseMode refers to pausing the cursor over something in the graphics window without clicking any buttons.
A touchpad or single-button mouse can also be used. See also: device, Mouse Modes for Right Button toolbar, Marker Placement, ChimeraX window
Given without arguments, the mousemode command reports the current assignments in the Log. Initial defaults include:
- left: rotate
- middle: translate
- right: translate
- wheel (scrolling): zoom
- Ctrl-left: new selection
- Shift-Ctrl-left: toggle selection
Possible values of function are listed in the table below. They can be truncated to unique strings. If function contains spaces, it should be enclosed in quotation marks. Not all functions make sense for a given input mode; for example, only identify object and none are reasonable functions for pauseMode.
Multiple modifier keys and multiple “buttons” can be given in a single command, but all specified modifiers apply to all specified buttons. For example, two commands rather than one would be needed to assign functions to control right and alt wheel:mousemode control right 'rotate and select'

A click with a touchpad (trackpad) or single-button mouse is generally interpreted as left click, but can be combined with modifier keys to emulate middle and right:
Magic Mouse issue: if a trackpad is also present, scrolling with the Magic Mouse will not work unless multitouch actions are disabled in the Trackpad preferences (the Trackpad gestures option is unchecked).
