This has turned out to be remarkably simple. I'll provide my configuration file as an example:
section: screens
optiplex-380:
laptop:
hp7:
end
section: links
optiplex-380:
left = laptop
right = hp7
laptop:
right = optiplex-380
hp7:
left = optiplex-380
end
section: options
keystroke(alt+right) = switchToScreen(hp7)
keystroke(alt+down) = switchToScreen(optiplex-380)
keystroke(alt+left) = switchToScreen(laptop)
end
As you can see the addition of the "section: options" with a keystroke and the switchToScreen function seems to be the ticket here.
