Shifted notes

normalshapemediumseriesnormalshapemediumseries\rqu :
acts like normalshapemediumseries\qu but the note head is shifted one note width. This is used for chords with upper note on the right side of the stem.
normalshapemediumseriesnormalshapemediumseries\rql :
same with stem down.
normalshapemediumseriesnormalshapemediumseries\rhu :
same as above for a half note, stem up.
normalshapemediumseriesnormalshapemediumseries\rhl :
same with stem down.

In addition on can use the command normalshapemediumseriesnormalshapemediumseries\roff to offset any note character by one quarter note head, e.g.:

\roff{\zqup h}

which will post a pointed quarter note with stem up, offset by one quarter note head with respect to its normal abscissa. \roff{...} is heavily recommended instead of \qsk if the score is intended to be run also with MusiXTEX.
