I'm trying to adjust a simple template in Pages version 5.2 but can't for the life of my figure out how to change the existing layout such that the text spans the full width of the page.

I've turned on `Show Layout` and tried adjusting the left `Document Margin` to 0 but it's still indented by about 4.5cm and that throws the footer and header too far to the left.  The Ruler won't allow me to drag the slider any further left than the edge of the layout.

Changing the `Column` settings doesn't do it either. My `Indents` settings are all set to 0. I'm completely at a loss as to how to do this.

I've had no issue changing the top, bottom and right margins, but the left margin seems to have this welded in inset.

The following screen snap of the standard Business Letterhead template (_with markup in red_) indicates what I am trying to achieve.

My thinking is there is some weird margin applied, but I don't know where it is set. I can not move the blue tip (see image below)

How can the tip to the left be moved? Right now it is 'blocked'.
