# tty mode round-trip: Ctrl-b in, run a command, Ctrl-b out. Ctrl-b is the one
# switch between raw and normal. Shift-Esc (CSI 27;2u — needs a host that
# reports modifiers on Escape) never switches: in every mode it is what Escape
# is in normal mode — Last, the pane you were in before this one — and a raw
# terminal stays raw. The hop itself is covered by a unit test in pardes.zig.
