Editing navigation screen - enable and save buttons are offscreen

My touch screen is not wide enough to get to the save changes or enable customisation buttons. The last thing I see is the samba market. I have tried to adjust the screen but also no avail.

Edit, hack or fix?

Show a screenshot of what you mean? Also what size screen is it? I am able to view it on a 7 inch tablet.

EDIT: Emre suggestion should fix it. Nevermind my request.

Hold down shift + crtl keys, point mouse over sambapos logo and use mouse wheel to adjust zoom level until these buttons appears.

That worked nicely, thank you.
