Sorry if this has been asked before, tried to search but found little to go on. I do most of my work with the keyboard. Cinnamon seems to adapt to this well (minus the broken custom shortcuts which had to be enabled with an ugly-ish hack). In any case. when I enter expo with C-A-Down, I can then focus on a window via keyboard navigation. I can go to that application via enter. But as far as I have found, there is no way to close the application (for example, via Del, as can be done to take a workspace away in workspace scale) without clicking the X on the corner. Does such a function exist and I am overlooking it?
