Wireless keyboard Shift+Return not working
I have an Apple wireless keyboard Model A1314 paired to a MacBook Air, M1. also paired to the MBA is a Magic Mouse Model A1657.
recently, the Shift+Return key combination does not work. I use this to insert carriage returns on my Viber, Messenger, WhatsApp chats. the issue is on both Left Shift+Return and Right Shift+Return. when I try the Shift+Return combination on my MacBook keyboard, there is no issue.
the shift key works normally in other areas (capitalizing, shift+command+4).
I have tried connecting/disconnecting, unpairing/pairing. no change.
I suspect (but I will not swear in a court of law) that this started when I updated my MacBook to Venture 13.1.
any suggestions on how I can get my Shift+Return to work again?
