ANSWER--

When you can edit what is there you just place the cursor from where you need to start selecting and press and don't release shift and select by pressing right arrow key. When you are done copy it or whatever you want to do with it

Another way, which is more easier is pressing the left mouse key and without leaving it take the cursor till where you want to select
