Bring to top current window
Sometimes you want a window to be visible even when you are working with a different application. For example it contains instructions you have to follow, or it shows the progress of a lengthy operation you want to monitor.
In these cases it is very convenient to have a way to temporarily turning it in what is known as a "topmost" window. A topmost window is kept on top of all other windows, even when it has not the focus because you are working with other window.
First, you have to check the 'Set to top current window' option on the Keys, tray and activation tab of the Configuration dialog, and define a key combination, or use the default value.
To make the current window a topmost window simply press the defined Hot Key combination. Pressing it again will turn it back to a normal window (which only is on top when it is the focused window).
