My up arrow stopped working on it's own...both on my laptop keyboard and on my bluetooth apple keyboard. If I use it as a shortcut, like Shift+Up, Fn+Up, Cmd+Up, etc., it works as normal....but by itself there's no response. Really frustrating in that I can't quickly move objects, go up a cell in a spreadsheet, scroll slightly in a browser, etc.
The other arrow keys work as normal. I checked and I don't have any keyboard shortcuts assigned to the up key. I haven't been able to find any good posts about this issue.
Any help?

If no resolve— To trouble shoot further you can:
—Try a SafeBoot https://support.apple.com/en-us/HT201262
Takes noticeable longer to get to the login screen, does a 5-15 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc. Login and test. Reboot and test as caches get rebuilt.
In Safe mode third party system modifications and system accelerations are disabled, it removes malware, etc hampering smooth operation, however a reboot will put it back to normal mode.
This test will tell you if third party interference; extensions etc are not loaded in safe boot mode.
—Test issue in another user (or guest user) account https://support.apple.com/en-us/HT204443
This will tell you if it a universal issue or isolated to your user/admin account.
