The structural piece: a global SequenceMatcher in root_shell, at the
HardwareKeyboard level so a focused editor/pane can't swallow the second
chord. It only STARTS on a modified chord that prefixes a sequence (ctrl+w),
so bare-key sequences (gg, dd) stay editor/pane-local and single-chord presets
are untouched; bare ctrl+w still fires editor.close after the D-82 timeout.
vim.yaml binds the window family under vim.normal||vim.visual: ctrl+w h/l →
panel.focus.left/right, j → dock.toggle, w / ctrl+w → focus.nextPanel,
shift+w → focus.previousPanel, o → panel.focusMode, q/c → editor.close.
Tests: ctrl+w sequence resolution at the keymap layer, plus app-level
integration (ctrl+w o toggles focus mode; bare ctrl+w closes the editor after
the timeout; a bare g is not grabbed globally).
This is the global matcher T-405 part 2 (gt/gT) was waiting on — though bare-g
sequences need more thought (g is editor-local), noted for that follow-up.
