How to insert colon at the start of every indentation
Hello,
I want to insert colon after every indentation to an existing text.
Example:
My current text is like this:
JOHN Good morning!
JACK Good morning!
And I want it to be like this (with a command) because the existing text is very long to enter them manually, one by one.
JOHN : Good morning!
JACK : Good morning!
What do I need to do to insert colon in every line after second indentation?
Thank you in advance.
