The Magic Dot: Repeat Command
Task Instructions
Learn the powerful dot (.) command to repeat your last change
Fix the first typo manually using 'x' to delete the extra letter, then navigate to similar typos and use '.' to repeat the deletion. This teaches the powerful pattern of 'do once, repeat many'.
Learning objectives
- Master the dot (.) command to repeat changes
- Understand how to efficiently fix repetitive patterns
- Build muscle memory for the repeat workflow

What This Means

Hints
