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 (๐). You can directly play just the audio from this section by clicking the Play button (โถ๏ธ).
Finally, click Replace all to confirm your choice!
