The movetext plugin is designed to change the position and/or color attributes of existing text. You may also set up a condition such that the text is moved only when the condition is met.
To edit a block of text in a document with movetext, it must first be defined as a field, see Attaching a plugin to a field. Clicking Configure then opens the movetext dialog.
Move only feature
MoveText may be used to simply reposition non-text fields (drawn paths, shapes, images) on the page. Just set up the options in the Move selected field panel of the movetext dialog.
