Editing subtitle events
To edit a subtitle event, simply click on the event (or use the Edit subtitle hotkey) and start typing.
Alternatively, you can open up the events browser by clicking on the 'View events browser' button on the top toolbar, and type directly into the events there.
The 'View events browser' button looks like a small list.
Tip: when using the events browser you can also click on the Focus mode button in the bottom-right corner, to view the subtitles in the event browser exclusively.
