Fill a form field by field with ⌃⌘V, without switching windows.
Filling a form from another window costs one round trip per field: copy, switch, paste, switch back. Paste in order removes the switching.
Pasted rows are struck through, so you can see what is left. The run resets when you copy something new, search, switch tabs or close the popup.
Hovering a row and pressing ⌃⌘V continues from that row instead of the next one.
For anything longer than a handful of fields, use the Stack — it holds a queue of its own and can press Tab between pastes.
