FingerTips is a mixture between an application launcher and a text replacement tool that's intended to save you time and improve your productivity. However, not all that glitters is gold and FingerTips has some issues that prevent it from being a really handy app.
The program has two main functions: one is launching applications just by entering the hotkey that you have previously assigned to it. The same applies to opening folders: it doesn't work on a search-as-you-type basis, but rather on a user-created acronym method. Also, Fingertips seems to be very much oriented to working with Outlook, as you can tell from the amount of key shortcuts dedicated to specific functions in this program.
The other function is replacing hotkeys with longer strings of text, which is supposed to save you loads of time and typing especially if you tend to write the same texts over and over again. Unfortunately this feature didn't work properly for me: I created new hotkeys but they never got replaced by the original text, and sometimes the program crashed while working on it. So while I wait for a future version that will hopefully solve these issues, I recommend you to use Launchy or Texter instead.
While the aim behind Fingertips is certainly a very interesting idea, the program still needs some further development, as it falls short of expectations.
