Not really a zsh thing, just a curiosity

[Bart Schaefer]

I've somehow gotten one of my gnome-terminal windows into a state where
in one tab the mouse wheel scrolls back through the window buffer and in
the other tab the mouse wheel scrolls through the zsh history at the
command line.  I have no idea how this happened, and I've never seen the
latter before.

There are two terminal modes regarding mouse: one when mouse is completely handled by a terminal emulator itself and one when terminal emulator only translates mouse events (wheel, presses) into escape sequences. Of course, modes are switched by passing terminal emulator some escape sequences. According to http://invisible-island.net/xterm/ctlseqs/ctlseqs.html this is not all-or-nothing thing: you may choose which of the mouse events are handled by the terminal and which by the application. Search the referenced page for `(?i)mouse`.

Guessing that scrolling the window buffer is default behavior and you put
one terminal into normal vi mode (though I guess it's possible to do this
in emacs mode - IDK how).

You've entered the alternate screen ($terminfo[smcup]). In
there, there's not scroll buffer, so gnome-terminal choses the
map the scroll wheel events to the same sequences as the arrow
keys.
