Purpose
To increase or decrease the contents of any other numerical input box interactively.
Usage
Click the +/- input box to activate it. Next, activate any other numerical input box (red outline). If you keep the middle mouse button pressed down, you can move the mouse up and down and the contents of the selected input box will follow. To confirm, press the left mouse button.
Comments
The numerical value of the selected input box will change when the mouse is moved. The resulting new value will be fixed by pressing the left mouse button. When the right mouse button is pressed the changes made so far will be canceled. It is not possible to select any other input box than a numerical input box. Selecting an input box with text content will deactivate the +/- input box. The size by which the +/- function increases or decreases the selected numerical values is set by the step input box.
