acme mouse chords: 1-2 Cut / 1-3 Paste while a left selection drag holds (both in one hold = Snarf/copy; the chorded left release is inert), plus 2-3 / 3-1 / 3-2 cancel an execute or look drag mid-gesture (the 2-1 argument chord already existed). chordcut.snap covers cut/copy/paste and both cancels; tutor documents the chords.
