I think my question is related to this post but I don't have ccsm installed at the moment, and I don't want to unless I have to (some of the things you can change in there can cause quite a lot of mess).
I am using Unity Tweak Tool, in particular to customize the behaviour of window snapping (top:maximize, left:left-half, right:right-half). However, when I activate this specific option, it seems to override my keyboard shortcuts CtrlSuper+↑/↓/←/→, which I normally use to move my windows across desktops.
I don't understand why Unity Tweak Tools would activate keyboard shortcuts for a feature that involves dragging the window around, and most importantly why these shortcuts would override mine. What is the easiest way to disable keyboard shortcuts for window snapping while preserving the feature using mouse-drag?
