de.wikipedia : Tastenkombination Strg+F wirkungslos > persönliche Testphase sofort wieder abgebrochen --~~~~
Topic on Extension talk:CodeMirror
Yes, we're working on this problem. Strg+F works if the text is visible in the edit window (or just below it). It doesn't work for text that's further down on the page.
This problem has been solved on another website (GitHub), and we are working on adapting their solution. Thank you for writing.
