How do I create a macro that converts lines to a numbered list?

Explanation

This simple macro inserts a list number prefix at the beginning of each line. Combined with visual block increment, it creates proper numbered lists.

How it works

1. qa — start recording
2. I1. — insert 1. at the beginning of the line
3. <Esc> — return to normal mode
4. j — move to the next line
5. q — stop recording

Example

apple
banana
cherry

After qa I1. <Esc>jq and 2@a, then fix numbers with visual block and g<C-a>.

Tips

• Use the counter technique for proper auto-numbering
• Or apply 1. to all lines then use g<C-a> to fix numbers
• For markdown lists, use - instead of 1.
• Combine with :g/pattern/normal @a for selective application
