I know this may not seem like a super time saving technique, but the way you name your variables will help save time and reduce compile time errors.. Having a conventional variable naming format will help keep things organized and easy to read.
Styles
Typically, most variable names get the every other word capitalized. Functions get the first letter of each word capitalized and constants get all of the letters capitalized.
Example:
Variable: First letter of every other word capitalized.
Functions: First letter of each word capitalized .
Constants: All capitals
Of course, sometimes choosing a good variable name can take a long time!
