Larry,
I use Word Perfect.
I download all my lyrics(copy and paste) into Word Perfect, convert them to caps and then copy and paste to Notepad (or Wordpad if you prefer)for use in KHP. Here's a good source for lyrics.

I believe MS WORD also has the capability to change text to caps, but I already had Word Perfect on my computers and was used to using the program.
Hope this helps.
Take care,
George
