google-chromemacosmojave
I just upgraded to macOS Mojave and noticed something weird. When using Google Chrome, I cannot copy and paste with keyboard shortcuts. I thought maybe the keyboard was broken, but it works in other apps. I can copy and paste using the Edit menu or by right-clicking, so the contents are definitely getting copied.
Chrome is up to date. I assume if this was a widespread issue, they would've fixed it by now.
Any idea of how to fix this or what might be happening?
Given that this is almost certainly not a hardware issue (there is, after all, no copy/paste chip that performs that function) and given the troubleshooting steps you have included, this still sounds like a task for your local Genius Bar. If it's a configuration issue or a software conflict, they can help you sort it out, and if it's a bug in OS X, they'll make Apple aware of it so it can be fixed.
As other answers have mentioned, you still have to isolate software as a cause by trying a new user or a new install of the OS (perhaps to an external drive).
Ahhh this is embarrassing. Seems like this is a hardware problem. I tried following the steps Apple support suggested, and when I do the keyboard input identification in System Preferences OSX tells me my keyboard isn't recognised. I've just remembered I scrubbed the keyboard with a cleaner cloth a few weeks ago to try and get rid of the yellow grease it had accumulated - I guess this must've messed it up. Sorry Mavericks! Thanks a lot for your help Asmus!
Lesson: wear gloves when using white keyboard.

Just for fun while we are waiting for Google - Chrome to fix it.
