Greetings,
If I type a line, before I hit enter I can backspace or arrow around the line to edit it. This is very convenient when you type in a long line and realize you made a typo somewhere in the middle. You are able to correct the problem without retyping the rest of the line.
Unfortunately, sometime you want to copy from somewhere else, paste the line where you are, and then make a small edit to it. Aplwrap will allow you to edit a line you type but not a line you paste. Treating the paste like a typed in line is very beneficial.
Thanks.
Blake
