“Normal readout” means the standard display – the current value of the variable including its name, and the possibility to edit the value. “Large readout" will display only the value (with the variable name) in large font, with a possibility of editing. Selecting the slider option displays an additional slider to change the value of the variable. The last option hides the display of the value on the stage. If the slider is displayed in the context menu, there is an additional option for selecting a minimum and maximum value for the slider.
