Function Key Alternative

[Blaqdymun]

Hi Everyone, It's been a long while since I have had to ask a question but I must find this program...

Before I get blasted... YES, I did search but still couldn't find what I was looking for!

I currently swap between the Touch & The Mogul (depending on how I feel and which one fits into my cute little purse that day) and I remember when customizing my Mogul when it was released last year, downloading a program that allowed you to bypass using the function "fn" key when texting by holding a key down for a few seconds for a symbol and quickly double clicking to use a capital letter.

Come to think of it... I may have had it on my Treo 700p as well. Does anyone know of or remember what program this may have been? Please help me figure this out. I would much rather have this option than using the function key all the time... Thanks in Advance. Its some type of Keyboard hack.
