there are already keyboardshortcuts, the left one right screen bottom, for examle, is done with and 'tab' and 'F1', and so on. so this makes it impossible to use it with snatch because it uses two keystrokes. i already had an screen made for these buttons...
top left toolbar use 'shift' 'F1'-'F12' top right toolbare use 'alt' 'F1'-'F12'
so for fade changes you have to drag the toolbar with 'fadechanges' from the programmerscreen to any softbuttonbar and use a combination to enable it.
i tried it on the top rightscreen, and it behaves a little difrent then i expected, when the 'fadechanges' button is on the third position, you'll need to enter 'alt' 'F5' to toggle the button. the windowtoolbar was working normally, except ofcourse 'alt' 'F4', because that is the fast way to exit the programme you are working in.
