# tty n/N token motion (normal mode only): n/N SELECT the next/prev
# whitespace-separated token that look resolves — several per line, so the
# greet ls row hops big.txt -> plain.txt -> sub — moving the cursor to the
# token start and opening NOTHING. Return looks the selection (dir -> shell
# +ls there, file -> pane) and focus follows what opened. The first n wraps
# from the prompt row to the first token; insert-mode n still types; and a
# pane with nothing look-able in it never traps the walk, because the walk is
# a RING ACROSS PANES rather than a scan of the one you are in.
