# A tag's normal mode is the body's: h/l/w move in the tag's own text, and
# moving between panes is the window keys' job from a tag as from a body --
# there are no tag-only hops. `:` is the one key a tag and a body do not
# share: from the body it focuses the pane's own tag, from the tag it hands the
# keyboard back to the body. Each tag remembers its cursor; the first time
# there is nothing to remember and it starts on Save.
#
# Evidence is the `cursor=` header (the ACTIVE pane's cursor, which while a tag
# is focused sits on THAT pane's tag row) plus each pane's layout box, which
# carries its BODY mode as one character: ` ` normal, `^` insert, `$` tty. The
# tag has a mode of its own, so the box never changes while a tag is used.
