your keyboard may be labled strangly. if you have a
101-key keyboard, the delete key should be in the lower
left in the set of six above the arrow keys to the right
of the querty layout.
here's a picture

if that doesn't work, perhaps backspace
and delete have been swapped?
in all cases <compose>+X007f will get you an according-to-hoyle
delete. to type this double-vulcan nerve pinch on a pc style
keyboard, hold down <alt><shift>X at the same time then
type the caracters '0' '0' '7' 'f'. (no need to sacrifice a goat. a chicken
will do.) this is 007f is the unicode codepoint which corrisponds
to <del>. i don't know what <compose> maps to on non-pc
keyboards.
