to texture coordinates.
S, T, U and V are the standard names for texture coordinates in the
literature, just like X, Y & Z are standard names for 3d coordinates and
R, G & B are standard names for colors.

the reason why the help-file doesn't mention much more, is that it would
become impossible big.

i think a basic understanding from what [pix_coordinate] does can be
guessed when playing a bit with the help-patch and feeding it with your
own values.
