You're welcome. I discovered it myself only around 6 months ago, and so far I've found it to be very useful.

Their website lists a lot of different potential applications, but I use it almost exclusively for entering passwords from KeePass. In addition to allowing password entry on the computer's lock screen, it also saves me the trouble of having to read and retype passwords manually on computers that don't have KeePass installed, and avoids exposing my entire password database to the computer it's plugged into (as would be the case if I used portable KeePass on a USB memory stick).
