How do I increase viewing size of camera?

I would look in FAQ but I don't know what the name of the dotted line bar is.

I'm new and all that so construct is all greek to me, however I think I am getting the hang of it! I haven't been able to find tutorials on how to increase the view of the player however.

Increase the view? - In size?

Make the player sprite size bigger and/or change the scale of the layout and/or reduce the size of the layout / window.

Go to the bar where all of your sprites are then click the folder that says New project or the name of your project after that go to the properties bar and you will see a load of different things you can adjust and just go to the camera bit and adjust it.
