An sxhkd chain (alt + w ; h) is realized by the engine: after the prefix only the keys that can come next and Escape are grabbed, because KWin 6.8's own key sequences never fire. What ends a chain that nobody finishes is the chord timeout, and the engine has no clock: it is told the time with on_tick. Rather than ticking on a timer forever, the engine now says when its pending chain times out (Engine::deadline, in komorebi-hotkeys) and the transport sleeps until then, calls on_tick, and grabs the keys of the mode again. With no chain pending it does not wake up at all. The daemon takes --chord-timeout in milliseconds, 3000 by default, the engine's default and the module's chordTimeout to come. A unit test follows the calls of a chain from its prefix to its deadline. The VM test vm-keys-engine grows a section with an sxhkdrc passed as --keybindings and a timeout of 1.5 s: Alt+W, H runs the binding and H does not reach wev; Alt+W, Escape lets the next H reach wev; Alt+W and two seconds later L reaches wev and runs nothing.
