You can perform both the Undo and Redo functionality easily in PDF Suite.
Undo lets you annul the last action that was just performed. There are two easy ways for you to do this. In the top left corner, above the main menu, you will see the backward arrow indicating the Undo feature:
You can also perform this function by holding down the CTRL + Z key on your keyboard.
Redo allows a user to redo anything that was previously undone with the Undo feature. You can use this feature by clicking the forward arrow next to the Undo arrow. It will be grayed out if you have not already used the Undo feature.
You can also Redo by holding down the CTRL key and then choosing the letter Y.
We also have the OCR (Optical Character Recognition) module that allows you to recognize and edit text within any scanned document or image.
If the OCR module is not available for you, you can purchase it here.
