Here's a description of Terminal Helper:
"DO NOT USE ENTER in Command!
This application is designed to help people working with SSH/ConnectBot/Terminal applications with possibility paste something into it. You can make list of often used long commands here and then map Terminal Helper to some shortcut key on your keyboard, and pick any of these commands just with one click to your clipboard.
Also, you can use word #customString# somewhere in your command line (so many times, as you wish), and Terminal Helper will ask you for replacement every time before copying command to clipboard.
