Unused symbols

The ASCII characters 6, 7, 8, 9, 0 and , are not used to represent anything in NetHack by default, although [,] is the pick up command.

Many players like to change the boulder option to "0", which is a better graphic representation of boulders, and far easier to see than "`".

Some players also change the "monsters" option in the options file to take advantage of one of these unused symbols. A default line looks like:

OPTIONS=monsters:abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ@ '&;:~] One alternative is:

OPTIONS=monsters:abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ@8'&;:~]

which uses "8" for ghosts and shades. This makes them detectable via telepathy as well as generally easier to see.
