You can move form fields in a PDF file by dragging, using keyboard keys, or with the Cut and Paste commands.
To move a form field, approximately position it by dragging it to the new location. To limit movement to a horizontal or vertical direction, begin dragging and then press Shift as you drag the selection. Position the form field precisely with the arrow keys.
To relocate or copy a form field to the center of any page, select it, choose Cut or Copy at Edit > Clipboard, navigate to the desired page, and choose Paste.
Pasted Fields are placed in the center of the page. If further fields are pasted, they appear with an offset, lower and to the right of the first field.
Note
Do not edit form controls or run Form Typer on a form with active XFA controls.
