It was the case until recently that I could scroll up and down either within a Gmail message or on the page containing the message by clicking there (just to make sure the cursor/focal point is there) and then pressing Up Arrow and Down Arrow. I am no longer able to do this. Has this feature been intentionally removed, and if so, why? Is this an anomalous bug? Have others experienced this behavior?
Page Up and Page Down still work. I am using Google Chrome.
Update: Magically the feature is back on in Gmail! But still off in Google Apps mail.
