Many features in Mudbox are accessible using keyboard shortcuts called hotkeys. You can create and edit hotkeys in the Hotkey editor (Windows > Hotkeys). You can also assign hotkey settings from other Autodesk 3D applications for use with Mudbox. See Customize keyboard shortcuts.
Refer to the links below for descriptions of all default hotkeys. Note the following section if you are using hotkeys on a Linux system.
Most Mudbox hotkeys for Linux are the same as those described for Windows, and many use the Alt key. Since the Alt key is a default system hotkey on Linux, you want to change this mapping before running Mudbox on Linux for the first time.
