Actually, what I was looking for was indent, not tab.
And I found that in the menu.

Another question...
There is a region on the left margin to the left of the code and to
the right of the outlining area, in between the code and the
outlining area. It looks like an area used to select lines. But
dragging the pointer down that area does nothing apparent. Isn't
that supposed to select lines of text? Maybe I have colors set
wrong, but selected text does show up when selected other ways. Or 
maybe that area is nonfunctional, left over from the IDE?

Thanks.
