Textmate add multiline text at end of line

Solution 1:

Select all the lines you want to edit then type ⌥ + ⌘ + a. You will be able to edit each line simultaneously.

The command is called "Edit Each Line in Selection" and can be found in the "Text" menu.

Solution 2:

In textmate 2, make a vertical multiline selection (just ⇧-↓ to select multiple lines then ''tap'' the option key ⌥ to make a vertical selection)

Now.. just move to the end of the line (⌘→) - boom! you can edit the end of each line!

Lorem ipsum dolor, ADDED THIS TO EACH !!
consectetur, ADDED THIS TO EACH !!
do eiusmod tempor incididunt, ADDED THIS TO EACH !!
