Problem with cursor keys

[balanga]

I have recently noticed some strangeness with cursor keys.

This strangeness is manifested by the down and left keys only moving one position when I hold those keys continuously, ie if I want to get to the bottom of a file or move to the leftmost position I need to press the keys repeatedly to move a single position either up or left . With down or right I can to keep my finger on the key and the cursor goes to top of file or beginning of line until I release the key.

Does anyone understanding what I mean and maybe have an explanation for why this is happing?

This is 100% reproducible with my keyboard when I eat while programming. No more Doritos for you and a cleaning out the crumbs should work. Flip it, shake it, gross out.

If you are using X, run x11/xev and check whether events continue to be generated while you hold down the key.
