    to move the editor cursor (it has to be placed somewhere before) to a given alignment position type a (position) number in one of the 'Position' (absolute alignment position - characters and gaps), 'E.coli' (homologous position in the E. coli standard), 'Base' (position in the current sequence - only characters, no gaps) or 'Helix #' (5'-end of 3' helix half; type a '-' for 5'-end of the 5' helix half) and move the mouse cursor back to the editing area of the ARB_EDIT4 window.
    to move the editor cursor to the next character (gap symbols neglected) press the 'ctrl' and one of 'right', 'left', 'up' or 'down' keys.
