The "knob" command is used internally by MGED in the processing of knob input devices and is not recommended for users. The knob command provides a method for simulating knob input. With no options, it will display the current values for the knobs. With the zap or zero command provided, all the knob values will be reset to zero. If an id and value are provided, the specified knob setting will be simulated. If the -i option is specified, then the value provided will be used as an increment to be applied to the indicated knob. The knobs have different functions depending on the current mode. For example, if in primitive or matrix edit mode and a rotation or translation function is selected, the knob effects are applied to the edited object by default. However, the -v (view coordinates) and -m (model coordinates) options may be used to adjust the view without modifying primitives or matrices. The -e option allows the knob effects to be applied to the edited object when they would normally be applied to the view. The -o option allows the origin of rotation to be specified with v, m, e, and k, indicating view, model, and eye and keypoint, respectively. The units for value are degrees for rotation and local units for translation. The available knob ids are:
