Quick guide to text cases
Title case vs capitalize words
Capitalize Words capitalizes every single word. Title Case follows headline rules, so small words such as of, and, the and in usually stay lower case unless they start the title.
Sentence case vs title case
Sentence case reads like normal prose, with a capital only at the start of each sentence. Many modern style guides prefer it for headings and interface text because it is easier to read.
Underline and strikethrough
These two tools add Unicode combining characters to each letter, so the line stays with the text when you copy it into a bio, post or chat. They are real characters, not formatting.
