- @quickhelp: KMdiTaskBar

- This window lists the currently open windows.<br>
- Each button corresponds to a single MDI (child) window.<br>
- The button is enabled (clickable) when the window is docked , and can be
- pressed to bring it to the top of the other docked windows.<br>
- The button text becomes red when new output is shown in the window and it is not the active one.<br>
