I am just beginning DraftSight.  A long time ago, I used a program called Drafix.  So, my two questions are elementary.

1) I zoomed in so much, that I lost sight of my drawing.  On Drafix, I would hit "View Extent".  That would bring all elements of my drawing back into view of my monitor.  How do you do that in DraftSight?  I see my work in the Sheet 1 tab, but not in my Model tab.

2) I don't like the dynamic zoom.  I much prefer to zoom in using a selected window like in PDF.  Which icon is this, and how do I get that icon to display on my toolbar.  I tried the obvious, but it doesn't work.
