Held alphanumeric keys should repeat
Holding down alphanumeric keys (like in VI to move within a file) does not work - you have to perform individual keypresses. Every character I tested other than [a-Z] and [0-9], DO repeat when held, but letters/numbers do not. This is very annoying when using VI, for example.
Alphanumeric keys should repeat in the same manner as all other keys.
