So after looking closely at my titles and considering a bit further, I 
believe that my original idea of doing this will not really solve my 
problem. There are a large number of tiddlers whose title is the same for 
up to 10 or 12 characters. I need to rethink a better way to navigate 
through all of the choices without creating a lot of clutter or a huge 
scrolling list. I am very open to suggestions.
