Biomechanics & Muscle Memory Tips
- 1Practice uppercase SQL keywords (SELECT, WHERE, JOIN) using smooth opposite-hand Shift holds instead of CapsLock.
- 2Drill underscore (_) chording so snake_case column names feel as natural as plain prose.
- 3Read two tokens ahead of your cursor to anticipate parentheses and table aliases seamlessly.
