Having text selected in Quiz and Knowledge Check could save a lot of time...

In any quiz or knowledge check it's a bit annoying to have to first select the text to delete it and then type... It would make sense that it is the text should already be selected so you could skip the extra step. 
The process should be smooth. Even when pressing tab it does not select the next text. 

Although this may sound trivial it really adds up and could save time.
