The ui command adjusts the user interface (UI):
Several ui subcommands set generic tool-interface preferences.• 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.
• ui favorite true | false tool-name
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.
• ui fullscreen true | false
Whether the tool should be listed in the Favorites menu; saved in preferences. Can also be adjusted through context menus.
Make the ChimeraX window fill the screen and hide its title bar. See also: camera, Window preferences, using ChimeraX fullscreen
• ui menubar true | false
The tool command (same as ui tool) shows or hides the user interface of the specified tool. Example:tool show "Side View"See also: Tools menu
• ui statusbar true | false
Show/hide the ChimeraX menu on Windows.
Show/hide the status line.
The functionkey command (same as ui functionkey) assigns ChimeraX commands to the keyboard function keys. The key can be given as F1, F2, etc., with or without capitalization. The wordlist may contain one or more command(s) and their options. If multiple commands are included, they must be separated by semicolons and the entire wordlist enclosed in quotation marks. If no wordlist is given, the key's current function is reported in the Log. If no key is specified, any/all function-key assignments are reported. Function key assignments are saved as preferences. See also: alias, buttonpanel, mousemode• mousemode [ control ] [ alt ] [ command ] [ shift ] [ leftMode function ] [ middleMode function ] [ rightMode function ] [ wheelMode function ] [ pauseMode function ]
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. 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 selected models'
mousemode alt wheel contour
A trackpad or single-button mouse can also be used. Given without arguments, the mousemode command reports the current assignments in the Log. The analogous command for virtual reality hand controllers is vr button. See also: cofr, device, functionkey, ChimeraX window
The mousemode setting command allows adjusting the speed or sensitivity (default 1) of contour level, zoom, and any of the rotation and translation functions. Specifying a speed but omitting the function adjusts the sensitivity of all applicable modes, whereas entering mousemode setting without arguments reports the current value(s) in the Log. Sensitivity changes do not apply to multitouch gestures, however.
Summary of mouse and trackpad default assignments:
rotate left mouse button trackpad click-drag
Mac: also trackpad 2-finger rotation if multitouch gestures enabled
translate middle mouse button Mac: trackpad + Alt, 3-finger drag if multitouch gestures enabled
Windows: trackpad + Ctrl-Alt
+ Shift switches from rotate to translate and vice versa zoom mouse scroll wheel Mac: trackpad pinch or 4-finger drag if multitouch gestures enabled, otherwise 2-finger drag
Windows: trackpad 2-finger drag
select left mouse button + Ctrl, + Shift to toggle or add to selection trackpad + Ctrl, + Shift to toggle or add to selection
The right mouse button (= trackpad + Alt on Windows, trackpad + on Mac) is also assigned to translate by default, but can be reassigned by clicking an icon in the following tabs of the Toolbar:
- Right Mouse:
- Medical Image (just the last section, which contains a subset of the Right Mouse icons)
Details on the functions are given below. The icon for the current right-mouse assignment is highlighted in the Toolbar. A specific mouse button can only be assigned one function at a time.
In commands, the function can be truncated to a unique string. If the string 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.

A click with a trackpad (touchpad) or single-button mouse is generally interpreted as left click, but can be combined with modifier keys to emulate middle and right:
With Trackpad gestures enabled in the Trackpad preferences, multitouch gestures can also be used on Mac trackpads: two-finger rotation, three-finger translation, pinch-zoom, and four-finger scrolling; with the setting turned off, a two-finger drag is interpreted as scrolling. Either way, if “secondary click” is enabled in the Trackpad system preferences, a two-finger click-and-drag performs the right-button action. Magic Mouse scrolling will not work after a trackpad has been used unless the Trackpad gestures option has been turned off.
