Windows contain standard sets of controls to help
you manipulate the application's data. The
figure below shows a typical application
window with some of these
controls.
Text fields provide an area where you can type
information.
Lists display a list of choices from which you can select.
Scroll bars provide a means to display text that
extends beyond a window's display area.

options and
settings. Types of buttons include push buttons,
toggle buttons, and
radio buttons.

Cutting and Pasting Text into Windows | |
Cutting and pasting eliminates the need to retype text.
You can cut from and paste into:
Cutting Text.
Move the pointer over the first character you want to cut.
Press and hold down mouse button 1.
Drag the pointer over the text you want to move. The text appears
highlighted.
Release mouse button 1 after all the text you want
to cut is highlighted.
The highlighted text is copied to an internal "clipboard". The text is not
removed from your original source.
Pasting Text.
Position the cursor where you want to insert the text.
Click mouse button 2.
A copy of the contents of the clipboard is pasted at the location you
indicated. You can make additional copies by repeating the above steps.
To unselect text, click mouse button 1 in an empty area of the window that
has the text selected, or press ESC.
When you cut text, it is stored temporarily in a buffer. This buffer
can hold only one item at a time. If you cut another piece of text
before pasting the first piece, the second piece of text will
overwrite the first in the buffer.
Choosing a List Item | |
A selected list item is highlighted. The selected item is acted upon when
a command, such as OK, is chosen.

Choose a command, such as OK.

default command.

reach your choice, then press the space
