Figure 1-15: Examples of show/hide
buttons
A similar capability exists in certain types of lists, where you can hide or show
details (list items) under a heading. Again, I’ll point out examples as they arise.
But you intrepid explorers out there should keep an eye out for these things. If
you don’t notice them, or don’t know how to use them, you’re not seeing all the
information that’s available to you. Using the + and – buttons in a list is easy:
✦ If items are currently hidden, click the + sign to expand the list.
✦ If items are currently displayed, click the – sign hide the list.
Figure 1-16 shows a general example.

Using Dragging Handles
A dragging handle (sometimes called a sizing handle, or even just a handle) is a
control that allows you to move or size an item by dragging. Dragging handles
come in various shapes and sizes, but as a rule they tend to look like little non-
skid areas, as in the examples shown in Figure 1-17. We’ll point out specific
examples as we go through the book. For now, when you see a little nonskid
area like one of the examples shown in the figure, know that it’s not just there
for decoration. Like everything you see on your screen, it’s a control that
serves some purpose.
