Shift States

Note how most of the letter keys are actually cased versions of each other (also note the light gray keys; those are dead keys). By convention, most of the letters that have a cased version will usually see that version in the shifted state. However, some languages have no notion of case, so they do not need to use the shift state for this purpose.
