Parm Slider is a powerful tool for interactively adjusting node parameters, going beyond the traditional use of the mouse wheel. This technology allows quick and precise modification of various parameter types—integers, floats, angles, as well as boolean switches—depending on how the parameter is described in the Parm Slider tool.
To adjust parameters, the user holds down a hotkey (default is Z) and moves the mouse cursor without pressing the mouse button: right to increase the parameter value, left to decrease it. For boolean parameters, a simple press and release toggles the state.
