You will notice that a number of buttons appear to come in pairs, like so:
Clicking the first button of this pair will insert a comment as shown below.
It might be tempting to browbeat the student into submission by continuing to
hammer on the first button for every pronoun agreement error in the paper,
overloading it with the same robotic comment. On nicer days, however, when
the sun is shining, and the administration is leaving you alone and not ignoring
you either, you will probably feel better just delicately indicating subsequent
instances of the same error with an abbreviated form of the comment above by
clicking Pronounce Agreement 2 (subsequent) button. How it looks to the
students appears below:
To make sure that students know what all the subsequent, abbreviated
comments mean, these shorter insertions are hyperlinked back to the initial
instance of the error. If students are in doubt, therefore, about a subsequent
comment, they can simply click it (actually, it's usually a control-click) and the
cursor will move back to the first instance of the error where they may re-read
the detailed explanation.
