***** The file that originally had to be edited was FalloutPrefs.ini - this has changed with the new Steam patch. The new file is now Fallout_default.ini in your Fallout New Vegas directory. *****
(C:\Program Files (x86)\Steam\steamapps\common\fallout new vegas, or a similar directory)
... need to go in your Fallout_default.ini under controls. Just copy and paste them in there under "bBackground Keyboard=1", or whatever the last line in controls is.
