Tab Order is Greyed out

I am using Acrobat 10 Pro/Win 11 which is a pain for setting tab orders. The document I have created for my client and I am working on is a 243 page form with over 3000 text and dropdown fields that need to be organized for tab order. Just loaded my Acrobat 7 Pro from 12 years ago on my 10 year old Dell XPS15/Win 7 and it is a breeze to set the tab order. Here is how it is done,

- Go to edit mode on Acrobat 7 Pro while working on your document

- Right click on any form field of a page 

- Select "Set Tab Order" from the selection pane (the tab numbers will be displayed on top left corner of each field"

- Click on the first field that you want to be tab number "1". The tab number changes as you click on the field. Stop clicking on the field when desired tab number is displayed. 

- Select the field you want to be tab number "2". Click on the field until the tab numbe "2" is displayed.

- Continue the process untill the tab numbers for all fields are set.

- Go to next page and continue the same process as above.

Hope this helps for those who are having hard time setting the tab order with newer versions of Acrobat.

Mmmm…

Calculation order and Tab order is not the same thing.

As you've mentioned, this is a very old version of Acrobat, not compatible with any current OS.

So unless you have something like Windows XP on it you should expect problems such as this one... In other words, it's probably time for an upgrade.
