Looks like Qt maps "Media Play" to the common play/pause button on keyboards: https://github.com/qt/qtbase/blob/5.15/src/platformsupport/input/xkbcommon/qxkbcommon.cpp#L293 https://github.com/qt/qtbase/blob/5.15/src/plugins/platforms/windows/qwindowskeymapper.cpp#L392 https://github.com/qt/qtbase/blob/5.15/src/plugins/platforms/android/androidjniinput.cpp#L519 https://github.com/qt/qtbase/blob/5.15/src/plugins/platforms/android/androidjniinput.cpp#L607 While "Toggle Media Play/Pause" is some special case: https://github.com/qt/qtbase/blob/5.15/src/plugins/platforms/windows/qwindowskeymapper.cpp#L488 https://github.com/qt/qtbase/blob/5.15/src/plugins/platforms/ios/quiview.mm#L584 It is worth to behave on "Media Play" like on "Toggle Media Play/Pause".
