Terminals send ESC [ Z for shift+tab, but the keymap had no binding
for it, so backtab presses arrived as unknown events and could not be
matched with (key-match? msg "shift+tab"). Bind [Z to
{:type :tab :shift true} alongside the other special keys.

What
Terminals send
ESC [ Zfor shift+tab (backtab), but the keymap had no binding for it, so backtab presses arrived as unknown events and could not be matched with(msg/key-match? msg "shift+tab"). This binds[Zto{:type :tab :shift true}alongside the other special keys.Why
Found while building a form wizard on charm.clj: Tab moved focus forward but shift+tab could not move it backward, since the event never reached the update function as a key press.
