play the same bar again

As a Unicode character — to paste into text, spreadsheets or chat. Whether it appears depends on the font.

In the score

A slash with two dots instead of a written-out bar. It saves space in accompaniment parts where a figure stays the same for a long time.

Photograph a page of sheet music or play the melody — Anotona finds the key, engraves the notes and transposes them into any other. Free.

Every note on this page is computed, not typed in — following the rule that also makes F# major spell its seventh degree E#, not F.
