Good to know
Toggle Case Converter looks at each letter and flips its case, so Toggle The Case becomes tOGGLE tHE cASE. Unlike alternating case, the result depends on what you typed, since each letter is simply reversed from its current case. Letters are evaluated as grapheme clusters, so accented characters flip cleanly, and non-letters are untouched.
Frequently asked questions
How is toggle different from alternating?
Toggle flips each letter from its current case; alternating ignores the original and uses position.
Are accented letters handled?
Yes. Letters are treated as whole grapheme clusters, so accents flip correctly.
Do numbers and symbols change?
No. Only letters have their case swapped.
