Modifying a script to work in the background.

[CoreyDC]

I have found this AutoIt script where you enter random letters, and It finds an english word made with those letters only, using a word list from a dictionary.
If someone wants to modify it, so that I won't have to alt-tab to use it, making it work in background I'll realy appreciate it, or if you can make a similar script in another language that works without having to alt-tab, I'll take it.

Please make it like after I press F2 the script will store the letters I press next, then after I press F3 the script will use those letters, and then it'll press "T" then write /Result.
Example : I press F2, I type "eesudcc" without alt-tabbing to the script's GUI, then I press F3 the script will then press "T" and type /succeed.

(The script and the words.txt have to be in the same place / couldn't add the code so I added an attachment with the code in it Anagram.txt)
