Don't know what I did????

Hi, yesterday i was recording and someone knocked on the front door so i took my headphones off and accidentally put them on my keyboard. When i came back my track had changed it had white lines at the start and end and when i highlighted audio it highlighted behind it instead of over it, so it was hard to highlight a small area exactly as i could only see the highlight behind the audio if that makes sense. Now it is automatically like that whenever i start a new project!

I don’t know what i clicked on the keyboard but i can’t find any way to undo it :smiling_imp:

Any help gratefully received!
I will have a go at screen shotting it.

If it looks like this, then you probably accidentally caught the F6 key:

Try pressing the F1 key to get back to the normal “Selection cursor”.
