Tips:
To copy text from a PDF document, use the Text Select Tool and the text will remain editable.
If the text you wish to copy is in a column, choose the Column Select Tool. The column select tool maybe be in a submenu of the Text select tool.
You can also copy text with the Graphic Select Tool, however, it will be copied as a bitmap image and will not be editable as text.
