Commenting tools are available only
in PDFs that have commenting enabled. PDFs in a review workflow
typically include commenting rights.
You
can use the Text Box tool
to
create a box that contains text. You can position it anywhere on
the page and adjust it to any size. A text box remains visible on
the document page; it doesn’t close like a pop-up note.
Another way to add a text box is simply to paste copied text into the PDF. Text font and size are based on the system default settings.
You can use
the Callout tool
to
create a callout text box. Callout text boxes are especially useful
when you want to single out—but not obscure—a particular area of
a document. Callout text boxes have three parts: a text box, a knee
line, and an end-point line. You can resize each part by dragging
a handle. The knee line can be resized in one direction only; horizontal
knee lines can be resized horizontally only; vertical knee lines
can be resized vertically only. The text box expands vertically
as you type so that all text remains visible.
You can move the text box bar itself or together with the end-point line. The text box moves around a stationary anchor point—the arrow on the end-point line—which is created when you first click in the PDF. You can modify the color and appearance of the text box and add arrows or leaders to the end-point line.
