After posting the drag and drop macro for powerpoint, I have been experimenting with macros to try and make instant changes to text and shapes in MS Office suite programs. I came across this brilliant site, Teacher's Pet.
Teacher's Pet Software - Turns any text into fun classroom resources, including crosswords, word search puzzles, bingo cards, flashcards and more.
From here you can download a free program that will enable you to play around with a host of ideas to manipulate chunks of text. I think this was developed with TESL colleagues in mind so some of the functions may not be appropriate for other languages, but I recommend that you have a look. Some features such as the flashcard, bingo and crossword generators have to be purchased but many others are free. This image file shows you the possibilities once the Teacher's pet toolbar has been installed on your version of MS Word.
Here is a video demonstrating how it works for one piece of text where I wanted to remove all of the vowels.
Update
Here is a link to a Word document which explains in detail all that you can do with this. Much of it is free but If you want to use the premium features of the software, use this code ‘ed7up’ to get a 10% discount at Teacher's Pet Software
