Module Review: Vim Grammar

[!NOTE] This module explores the core principles of Module Review: Vim Grammar, deriving solutions from first principles and hardware constraints to build world-class, production-ready expertise.

1. Key Takeaways

• Vim is a Language: Edit by combining Operators (Verbs) and Motions (Nouns).
• The Formula: Operator + Motion = Action (e.g., d + w = dw).
• Precision Matters: Use Text Objects (i for inner, a for around) to edit semantic blocks like quotes " and braces {.
• The Dot Command: The . key repeats the last change. Structure your edits (e.g., use A instead of $a) to make them repeatable.
• Efficiency: Don’t repeat yourself. If you do something twice, find a way to do it once and repeat it.
