Some modules with graphical functionality (GUI) have a Standby option in the module windows, e.g.
If it is selected and the window is open, then such a module waits for changes in the handling of the shock, e.g. placing a peak or location of the shock, and takes the appropriate reaction. The detailed operation of standby is described with a specific module.
Attention! In many modules, this option is future-proof yet and is currently ignored.
