When I press the 'Tab + W' keys and then press the Space bar, My iMac/MacPro keyboard only generate the 'Tab + W' events but not the Space event. Other combinations, such as 'Tab + A + Space', work normally, the 'WSAD' keys are typically used as the four directional keys in games and are often used in combination with other keys(Tab/Space), is there any solutions or advice for me to handle this issue? Thank you

I have noticed that external keyboards connected to an Apple computer support the simultaneous pressing of 'Tab + W + Space' keys, but the in-built Apple keyboard does not. When I press the 'Tab + W' keys and then press the Space bar, the Apple computer only receives the 'Tab + W' events but not the Space event. Other combinations, such as 'Tab + A + Space', work normally. Can you please explain why this is the case and provide any solutions or advice? Thank you
