How do I append the same text to the end of several lines?

Explanation

Selecting lines and running :norm A text appends the same text to the end of every selected line. This is often simpler than visual block mode.

How it works

1. Select lines with V and motions
2. Type : (auto-fills '<,'>)
3. Type norm A; (or whatever text to append)
4. Press Enter

Example

let x = 1
let y = 2
let z = 3

Select all three lines, run :'<,'>norm A;:

let x = 1;
let y = 2;
let z = 3;

Tips

• norm I// prepends // to each line
• norm! uses built-in key meanings (ignores custom mappings)
• More flexible than block mode for lines of different lengths
• :%norm A; applies to every line in the file
• Works with any normal mode command, not just A/I
