The document to be changed goes in the first slot. The first marker goes in the second slot. The replacement/second marker goes in the third slot. o ante will find all instances of the first marker and replace it with the second marker (find and replace). o ante will not work properly if the first marker is included in its entirety inside the second marker.
o weka will find every first marker/second marker pair and destroy them along with everything inbetween.
o mute is abit more complicated. It will find every first marker/second marker pair. It will then take what is inbetween them (but not the markers themselves) and make a copy of it that it places to the right of the second marker.
