Hi glorhee!
I think 5thWiggle means any input field in any app, or in the browser. Where you would put the curser and start typing, I think now you have to tap and hold in the box and you will have a choice of keyboard or diopen.
Disclaimer: I haven't tried this myself, just guessing based on the few things I do know!
Give it a try and see if it works! If you have the search box on your home screen you could probably try it there . . . let me know if I'm right (I so love being right!)
