I have been trying to make an array using a Custom Keystroke Script for a form field and after much troubleshooting discovered that for whatever reason trying to put the string "AF" into a var makes the entire script vanish when I click the OK button.
Using the following causes script to vanish.
var test = ["AF"];
I have tried the initialization in the Debugger and it works fine but it won't work in the PDF.
I also tested
var test = "AF";
that also doesn't work. Why can I not initialize the String "AF" using a Custom Keystroke Script in Adobe Acrobat Pro DC?
While testing I used the strings "Af", "BF", "ALFALFA", "AFTER", "AFRICAN" and "NAFTA", the first 3 work but as long as there is a capital "A" and a capital "F" in the string in that order it makes the entire script vanish. BOLD cause issue.
I go into edit Custom Keystroke Script:
![Step 1]()
I then type the offending var test = ["AF"]; and click OK.
![script]()
Then it drops me back out to this.
![After I click OK]()
When I go back in and try a different string it does this.
