Selecting tools
You select a tool by clicking its icon in the toolbox
or dragging to select its icon from a pull-out menu.
A small triangle to the right of a tool icon indicates
that the tool contains a pull-out menu of hidden
tools.
To select a tool:
Do one of the following: To select a visible tool, click its icon in the
toolbox. To select a hidden tool, position the pointer on
the overlying tool in the toolbox, and drag to high-light
the tool you want.
Use the following shortcuts to select
tools: To select a tool quickly, press its shortcut key
on the keyboard. These keys appear in the
illustration on page 17. To cycle through a set of hidden tools, press
Option (Macintosh) or Alt (Windows) and
click the visible tool, or press the hidden tool抯
shortcut key repeatedly.
Using the tool pointers
When you select most tools and position the
mouse pointer on the image, the pointer matches
the tool抯 icon. This is the default standard tool
pointer. The standard marquee, line, and gradient
pointers appear as crosshairs.
Each of the default pointers has a different hot spot,
the point where an effect or action begins. To use a
tool with greater accuracy, you can switch to pre-cise
pointers, which appear as crosshairs centered
around the hot spot. When you抮e using the paint-ing
tools, you can also display the pointer as a
brush shape reflecting the current brush size.
To set the tool pointer appearance:
1 Choose File > Preferences > Display & Cursors.
2 Do one of the following: Click Standard under Painting Cursors, Other
Cursors, or both to display pointers as tool icons. Click Precise under Painting Cursors, Other
Cursors, or both to display pointers as crosshairs. Click Brush Size under Painting Cursors to
display the painting tool pointers as brush shapes
representing the size of the current brush.
3 Click OK.
CHAPTER 2 22
Looking at the Work Area
When you抮e using the brush size pointer with very
small brushes, the brush shape is surrounded by
four dots for finer accuracy.

The Painting Cursors options control the pointers
for the eraser, pencil, airbrush, paintbrush, rubber

The Other Cursors options control the pointers
for the marquee, lasso, polygon lasso, magic wand,
crop, eyedropper, pen, gradient, line, and paint
bucket tools.
To change the appearance of some tool
pointers, press Caps Lock. Press Caps Lock
again to return to your original setting. The
following list outlines the pointer changes: Standard changes to precise Precise changes to brush size (painting

Using Palettes
Adobe Photoshop includes a number of palettes to
help you monitor and modify images. By default,
these palettes appear stacked together in several
groups. You can display and hide these palettes as
you work with an image.
To show or hide a palette:
Choose the appropriate Window > Show or
Window > Hide command.
Choosing a Show command displays the selected
palette at the front of its group. Choosing a Hide
command for a palette in a group hides the entire
group.
Changing the palette display
You can change the arrangement and display of
palettes and palette groups to optimize the work
area on your desktop. Use the following tech-niques
to organize palettes: Press Tab to hide or display all open palettes and
the toolbox. Press Shift+Tab to hide or display all
open palettes, excluding the toolbox.
