Datasheet

✦ Click an empty area on the scroll bar above the scroll box to scroll
up a page.
✦ If your mouse has a wheel, you can click on the scroll bar; then spin
the mouse wheel to scroll up or down.
✦ Drag the scroll box to any place on the bar to go to that part of the list.
Drag means “hold down the mouse button while moving the mouse.” In a
scroll bar you want to 1) Put the mouse pointer on the scroll box, 2) Hold
down the left mouse button while dragging the scroll box along the scroll
bar; and then 3) Release the mouse button when you get to wherever you
want to go.
Working scroll bars with the mouse can be a bit more challenging, because
there might be several scroll bars on the screen at the same time. The key-
board will work only one of them. For example, to use the scroll bar in a list
box control, you first have to move the focus to that control. Anyway, here are
the keys you use to scroll around using the keyboard.
✦ ↑: Scroll down a line
✦ ↓: Scroll up a line
✦ →: Scroll right a little
✦ ←: Scroll left a little
✦ Page Down (PgDn): Scroll down a page
✦ Page Up (PgUp): Scroll up a page
✦ Home: Go to the top
✦ End: Go to the end
Hiding and Showing Details
To keep your screen from getting too cluttered, Windows often hides some
information on the screen. There are plenty of examples sprinkled throughout
Windows, and I’ll point them out as they arise. But those of you who like to
explore on your own should be aware of how these buttons work, so you can
recognize them and use them as they appear on your screen.
The button you use to show or hide information usually has some sort of
arrow on it, or < and > symbols, sometimes pointing up and down. Figure 1-15
shows some general examples of Show/Hide buttons.
The Show/Hide buttons are simple to use — just click the button. If items are
currently hidden, clicking the button will take them out of hiding. If items
are currently displayed, clicking the button will put them back into hiding.
