-- Two panels side by side, with focus in exactly one of them:
|
|||
|
|
-- left -- the command list ("Menu – accept")
|
|||
|
|
-- right -- the keys currently bound to it, plus an "Add a new key" row
|
|||
|
|
--
|
|||
|
|
-- `currentlyActiveWindow` says which panel has focus, and both panels have their
|
|||
|
|
-- own selection index. Announcing the wrong panel's row would be actively
|
|||
|
|
-- misleading here, since the two lists are unrelated.

|
|
-- NOTE: this state is in hotkeys.lua's textEntryStates, so our own hotkeys stay
|
|||
|
|
-- out of the way while it is capturing raw keys for rebinding.
