Used for drawing attention to lengths of text. There are three types of markup annotations:
To markup the length of selected text with a markup annotation
select the text and then issue one of the markup commands (Text work
mode) or issue one of the markup commands first and then draw the
selection area (Edit Dynamic Annotations
work mode).
To markup blocks of text, rather than whole lines, first issue the markup command and then drag a selection on the page. When you release the drag any part of lines of text that fall under the selection are marked up.
If the selection rectangle does not cover any textual content a markup will be created the exact size of the selection rectangle.
