How'd you end up picking these shortcuts? IMO, we should generally avoid using meta shortcuts since those are typically intended for OS-level features that might conflict. Like:

meta + space: spotlight on macOS
meta + arrrow: window-snapping on Windows

I, for one, would find those particular overlaps to be pretty annoying if my VS Code window keeps moving around when I'm trying to move to specific columns, or spotlight keeps opening when I try to select a column.
