Access Find & replace by clicking the button at the bottom of the editor, just like in the screenshot below!
This will then open a pop-up where you'll be able to search for a word and make this correction across your whole transcript!
With this feature, you have some options to search for the exact word, whether the results should be case-sensitive or to maintain the capitalisation of the first letter.
In the results section, you can directly go to that section in the transcript by clicking on the magnifying glass (🔍). You can directly play just the audio from this section by clicking the Play button (▶️).
Finally, click Replace all to confirm your choice!
