Bug Report - In JavaScript, it's common practice to format the code to make it more readable by using the TAB key to indent text. This has worked fine in all previous versions of Adobe Acrobat that I've used. However, in Adobe Acrobat Pro DC, pressing the TAB key moves the text to the right once, as it should, but then the focus moves to the OK button to close the Editor. The focus should stay in the Editor so TAB can be pressed again to move the text further to the right. It is EXTREMELY inconvenient to have to click back in the Editor after every TAB, and in the EXACT same place you were editing, in order to TAB text further to the right. This bug was confirmed on two different machines running Pro DC and using both an existing form and creating a new blank document.

Steps to reproduce the issue:
1) Launch Adobe Acrobat Pro DC.
2) Select File > Create > Blank Page.
3) Select Tools > Rich Media.
4) Click Add Button on the toolbar
5) Click anywhere on the document to create a command button.
6) In the newly created button, click the All Properties link.
7) In the window that opens, click the Actions tab.
8) In the Select Action dropdown, select Run a JavaScript.
9) Click the Add button.
10) In the window that opens, type any text and then move the cursor to the beginning of that line.
10) Press the TAB key.
11) The text moves to the right 4 spaces, as it should, but notice the focus is now on the OK button.
12) Press TAB again and see the focus move to the Cancel button.
13) Click back in the Editor at the beginning of your text and press TAB again. Notice that the text moves another 4 spaces to the right, as it should, but once again the focus has moved to the OK button. This make formatting ones code ridiculously difficult.

Please fix this bug asap.
