The default setting is that the shortcuts for these actions are empty, which effectively means that they are handled like Qt handles them. And Qt uses Cmd+Left/Right for GotoLineStart/End and Home/End for GotoDocumentStart/End, because that is what macOS/Cocoa does (by default).

Thanks for confirming my suspicions then :)
