I’ve mentioned a few times in the past that there is a clear advantage to nesting window managers and/or terminal multiplexers on the same “desktop.”
Oftentimes that’s just because they work better together. For example, meshing dvtm and screen gives you the chance to keep three or four applications in a block, in one window. Neither by itself can do that, really.
Mod4 plus 9 triggers screen, which opens all the same programs in the places I expect them, same as on my terminal-only systems. And I still have the option to open things individually, if that’s what I’m after.
It might sound odd, but the real reason for that is screen’s copy-and-paste sequence. After you get used to moving text around with screen, the old way of click-and-drag is rather cumbersome.
Plus, I spend most of my time in screen, so I can usually work the keystrokes faster than reminding myself how to bounce between applications in Musca, all the while clicking and dragging.
So there it is again: something else that’s easier done via keyboard than by mouse. The list keeps growing. … 🙂
