My understanding is that windows are moved withint a screen using Win+Arrow and across screens with Win+Shift+Arrow. I would like to unify this, to move windows around without pressing shift.

In Windows, it it possible to move a window to, e.g., the left edge of a screen with Win+Left. A subsequent Win+Left press then moves it to (the right edge of) the monitor to its left. I find this simpler and also substantially quicker. Is it possible to replicate this behavior?

Alternating pressing shift is rather burdensome for me, as my fingers are not as quick and flexible as they used to be, and neither is my brain, for these split-second tasks that happen a thousand times every day.
