This bug vanished for a few days until yesterday it reappeared after enabling Zoom keyboard shortcuts. The original occurrence was after changing a Dictation preference. Yesterday I could repeatedly and reliably enable/disable it by turning Zoom keyboard shortcuts on/off but now it is stuck in the buggy state.

dtime is the time change, Δ=NS, δ=SDL NS time is NSEvent time = seconds SDL time is SDL_Event common.timestamp / 1000 = seconds Event and Details are logged by me, a Cocoa_PumpEventsUntilDate breakpoint and my SDL_WaitEventTimeout loop. NSEvent details are abbreviated, uncensored details follow. .c.. and .... indicate keystate[ SDLSCANCODE {LALT,LCTRL,RCTRL,RALT} ] decoded, followed by SDL_Event key.keysym.mod in hex and decoded, finally SDL_Event key.repeat decoded.
Peace

P.S. Surprise, having taken time to investigate NextStep events in Cocoa_PumpEventsUntilDate, turning Zoom keyboard shortcuts on/off controls the bug again, effective the instant I click the checkbox.
P.P.S. My SDL_WaitEventTimeout (&event, 1)
loop
burns 20% CPU hoping to promptly log SDL events
so they and my nonstop breakpoint po event
print (int)event.type
in Cocoa_PumpEventsUntilDate should output in temporal order.

SDL2 mysteriously started reporting spurious keyboard events, then mysteriously went back to normal about 28 hours later.
P.S. Nothing in MacOS changed prior to this lossage, except installing a new speech recognition language. No SDL apps were running when the syndrome began/ended. Multiple SDL apps were affected. No non-SDL apps were.
