Now that I have a new notebook running Vista Sp-1, I've gone nuts with my XP Pro machine. I'm indulging my software addiction on it and have LOTS of stuff installed (whereas the Vista machine stays lean so I can work with it). Thus, I have numerous file managers installed, numerous office suites, numerous... you get the picture. So... in addition, I have FARR, DirectAccess 2 beta, Dash Command, ActiveWords, and Humanised Enso installed and alternate between them. I also have QuickSilver installed on a Mac running Tiger and am very impressed by it, as well...
At the moment I am playing with Humanised Enso and am pretty impressed by it. Holding down the CAPS key isn't nearly as "bad" as I thought it would be, now that I've given it a chance and read the rationale behind it. Discovering that you can just select text, hold down the caps key and type "upp" and have Enso covert it to upper case removes my objection about occasionally needing the CAPS function.
