I am trying to edit text (insert text) in a pdf document using Adobe 9 Pro. When I click on Advanced Editing, touch up text tool. I select a box around the text and begin to type, nothing appears the cursor moves but nothing is typed. I need immediate help .
Editing text and Adding text require different tools.
The Touch up text tool would be used to modify; add, modify or delete within a line of existing text.
To add text to an open area, the Typewriter tool would be necessary.
Don't expect full editing abilities.
Actually, I would not use the typewriter tool for that. It adds an annotation, and that may not be what is needed.
Personally, I'd add text with the Touch-up Tool. Ctrl+click will allow it.
