Makes the window transparent according to percents from pop-up Transparency Menu
How it works
To make window opaque, you should choose item “100%”
in pop-up Transparency Menu.
For this button you may assign any valid keyboard and shift key (including <Alt> and <Ctrl>) combination for each of eXtra Buttons. Use of this combination will have the same result as pressing the eXtra Button.
Note! Input of two identical combinations of keys for various buttons is impossible. To setup Hot-key already used, change it for that button that uses it.
