Don't underestimate the advantage of being able to move the cursor anywhere in a few clicks without having to take your hands off the keyboard. It is much faster than a mouse. Also, you can save your elbows the pain of constantly reaching over for the mouse.

avy does more than just jump the cursor to a specific place. It also allows you search for, copy and move text round without needing to move your cursor to that text. It is extremely easy to use and very efficient.
