I'm sure there is a way to do this but I can not seem to figure it out. I will try my best to explain this.

I have a list with 20,000 lines in notepad++. I have two tabs open in notepad++. The right side tab is the main list. The left side tab is what needs to be added to the beginning of each line in the right tab.

Here is an image of my notepad++ to give you a better understanding.

I need to be able to do the following in an automated way as I have over 20,000 lines to do this way.

1. copy line 1 of tab 'new 7'
2. switch to tab 'new 6'
3. paste clipboard(line 1 of tab 'new 7') at beginning of line 1 tab 'new 6'
4. switch back to tab 'new 7'
5. copy line 2 of tab 'new 7'
6. switch to tab 'new 6'
7. paste clipboard(line 2 of tab 'new 7') at beginning of line 2 tab 'new 6'

I have both pasteitin and typeitin download but if i need some other program/app or if it's built in to notepad++ that would be great. I need to do this by the program itself or for me to only have to press a button to do each of these.
