Shift

As with most roguelikes, NetHack has more than enough commands to necessitate using upper and lower case letters. One usually accesses upper case commands by means of the shift key, although pressing caps lock will do so as well. Note that using caps lock is generally undesirable, since lower case commands tend to be for more common actions.

On this wiki, upper case commands may be referred to by one of (using the example of (P)utting on jewelry) shift + P, shift + p, or P. For consistency and because it also works with keyboard layouts that don't involve shift, please prefer P.
