Can't scroll through code using keyboard

[sterretje]

Did something change again

I used to be able to click in a code window in a post and use the cursor keys to scroll through the code.

Now I can only use the scroll bar at the right of the code window to scroll.

Hmm

It now works

You aren't having a good day, maybe refrain from playing with expensive or sharp things

Could be as simple as NumLock on/off inadvertently. Trips me up, now and then.
