How to find and replace text in Mardo

Press Command-F to find source-exact text, or press Option-Command-F to open Find and Replace. Mardo searches the real Markdown source even while the document is rendered.

Find text

1. Press Command-F or choose Edit → Find….

2. Enter the text or bounded regular expression.

3. Use Command-G for the next match or Shift-Command-G for the previous match.

4. Press Option-Command-G or choose Edit → Find All for the complete result set.

Find supports case and whole-word choices, wraparound, progress, and cancellation. Results belong to the document generation that was searched; Mardo does not apply stale results after the file changes.

Replace text

1. Press Option-Command-F or choose Edit → Find and Replace….

2. Enter the search and replacement text.

3. Replace the current match, or choose Replace All after a complete uncapped search finishes.

Replace All commits one document transaction and one Undo action. Replacement text is literal; regular-expression capture templates are not expanded.

Find while using Zen Mode

Find remains summonable in Zen Mode. Entering Zen Mode dismisses a Find or Replace bar that is already open, but Command-F and Option-Command-F can open it again.
