Labels
are basically noninteractive pieces of text placed on dialogs used to
describe a
control
(such as the slides shown in Figure 3-12) that
doesn't have a place for a description. Clicking
labels usually has no effect.

Figure 3-14. Labels are noninteractive captions for other controls (like these sliders) that don't have captions of their own

The important thing to note about labels is that they often contain a
single underlined letter. Holding Alt and pressing the key for that
letter will send the
focus to the next control. This is useful
because the input field in this example doesn't have
a shortcut key of its own.

Notes

Some labels allow you to select and copy text and are distinguished
because the mouse pointer changes to an
"I-beam" when over the label.
Strictly speaking, these are just standard input fields (without
borders) that have been made to look like labels. Examples of this
type of field can be seen by right-clicking on a file and selecting
properties.
