-- Workspace Switcher keybindings for Omarchy (Lua config, Omarchy >= 4.0 "quattro").

--
-- Two binds:
--   SUPER+TAB  opens the switcher as a plain picker: arrows/hover to select,
--              Enter or click to switch, Esc to close.
--   ALT+TAB    alt-tab style: opens with the next workspace pre-selected; keep
--              ALT held and tap TAB / SHIFT+TAB to cycle; release ALT to switch.
--              What a lone tap does is the "tapAction" setting (browse | switch).
--
-- Change `hold_mod` to "SUPER" (and keep or drop the plain picker bind) if you
-- would rather hold Super. Both replace Omarchy defaults: SUPER+TAB (next
-- workspace) and ALT+TAB / ALT+SHIFT+TAB (cycle windows).
