How to use the question marks


A question mark with blue bg and yellow fg is the button to show the documentation for each window.

If you click one, a popup help window will appear -->

You can move it by dragging the upper bar of the window -->

Texts with blue colors and underlines are hyper links, or you can highlight the corresponding window by moving the mouse on it. That will temporarily change the bg color to yellow --->

(In this example, the mouse was moved on "the window on the right", although the mouse was not captured.)
