Yes  it's a rather geeky app and you need to have a telnet client  such as the command line one Windows comes with that you can get in ""Turn Windows features on or off""  or PuTTY. But once you connect to it  it's very straightforward to use. Just type into the terminal window and your keystrokes appear instantly on the Android device. If you can't figure out telnet  there's another remote keyboard app out there that uses a web interface  but you still need to enter some numbers in a browser to connect. (Or buy a bluetooth keyboard  it's simpler still.) I prefer this one because I like the simplicity of telnet and like the ""send to PC"" button at the bottom right of the phone screen  to send whatever's in the text box to the PC. It's a great way to get URLs out to a PC (or send a bunch of text up to be processed with a regex and then pasted back to the phone) while you're using Remote Keyboard. Manual ROT-13 encryption is a strange feature to include  but alright I guess. I'd really prefer if there were an option to have real encryption  either with telnet over SSL (if the user can puzzle out how to create such a connection)  or even better  SSH.
