Saving custom workspaces

Now that you have learned how to customize your

working environment in Photoshop, the next step is

to save theme-related workspaces for different kinds

of tasks This will shorten your setup time when you

begin your work sessions.AIn Photoshop CS5, the

current panel locations are included automatically

when you save a custom workspace.★ Optionally,

the workspace can include custom keyboard

short-cuts, as well as menu sets, which control the color

label and visibility settings for menu commands

Your custom workspaces should reflect your

normal work habits (and by this we don’t mean

working late and sleeping late!) For example, to set

up a type-intensive workspace, you would open the

Character and Paragraph panels and assign color

labels to commands that you normally use when

creating text Or to create a painting workspace,

open the Brush, Color, and Swatches panels, assign

color labels to the brush preset commands, and

maybe hide some unrelated commands

To save a custom workspace: ★

1 Do any or all of the following:

Open and position all the panels in the desired

locations, panel groups, and docks

Collapse the panels you use occasionally to icons

and close the ones you rarely use Or if you

prefer to keep all your panels collapsed to icons

or icons with names, set them up that way now

Resize any of the panels, as well as any of the

pickers that open from the Options bar

Choose a thumbnail, swatch size, or other

panel display options from any of the panel

menus, or from any of the menus on the preset

pickers that open from the Options bar

Choose Edit > Menus and use the dialog to

assign color labels and/or visibility settings to

menu commands Save your changes to a new

menu set (To customize keyboard shortcuts,

see “Keyboard Shortcuts” in Photoshop Help; to

assign labels, see “Workspace.”)

2 From the Workspace menu on the Application

bar, choose New Workspace

3 In the New Workspace dialog, enter a Name for

the new workspace (include your own name, if

desired).B

4 Under Capture, if you customized the Keyboard

Shortcuts or the Menus, check those options

AThis is the panel setup in one of our custom workspaces.

5 Click Save Your workspace will appear in three

locations: the Application bar, the Workspace

menu,Aand the Window > Workspace submenu

➤ To edit an existing workspace, choose the

work-space to be edited, make the desired changes to

the Photoshop interface, then save the workspace

under the same name; click Yes in the alert dialog

➤ On a computer with dual displays, you can

distribute freestanding panel groups or stacks

between them and save that arrangement as a

workspace

➤ All panels that are open when you exit/quit

Photoshop will reappear in the same location

upon relaunch There is no longer a preference

option that lets you turn this feature on or off.★

To delete a saved custom workspace:

1 On the Application bar, click any workspace

except the one to be deleted.

2. From the Workspace menu on the Application

bar, choose Delete Workspace.

3 In the Delete Workspace dialog, choose the name

of the user workspace you want to get rid of,B

click Delete, then click Yes in the alert dialog

Resetting workspaces

Say you chose a workspace and then rearranged some

panels manually If you were to switch to another

workspace and then back to the first one, your

manual changes would remain (be “sticky”) Follow

the first set of instructions below to restore the

origi-nal settings to an individual workspace, or the second

set of instructions to restore the default settings to

all the predefined Adobe workspaces

To reset one workspace: ★

1 On the Application bar or from the Workspace

menu on the Application bar, choose the

work-space to be reset

2 Right-click the name of the workspace to be reset

on the Application bar and choose Reset

[work-space name] from the menu

To reset all the Adobe workspaces: ★

1 To open the Interface preferences dialog,

right-click a panel tab or icon and choose Interface

Options.

2 Under Panels & Documents, click Restore Default

Workspaces, click OK to exit the alert dialog,

then click OK to exit the Preferences dialog

BIn the Delete Workspace dialog, choose the user-created workspace you want to get rid of.

A Our new workspace (named “Elaine’s Workspace”) appears on the Application bar and on the Workspace menu.

Using the Application bar ★

Use controls on the Application bar to go to Bridge,

arrange and choose options for your document

win-dows, and access and save workspaces for Photoshop.A

In Windows, the main Photoshop menus also display

on the Application bar In the Mac OS, the Application

bar is docked in the Application frame When the

Application frame is hidden, the Application bar is

docked below the main menu bar; if you don’t see the

bar, choose Window > Application Bar

Using the Options bar

You’ll use the Options bar (Window > Options) to choose

settings every time you switch tools — and sometimes

to change settings while using a tool.BThe Options bar

is dynamic, meaning its features change depending on

what tool is selected and how that tool is currently being

used in the document Your choices remain in effect for

each tool until you change them You can move the bar

out of the Application frame by dragging its left edge

more acquainted with a feature of

the Photoshop interface that you will

be using constantly as you work: the

to arrange the panels onscreen Here you’ll be

intro-duced to the specific function of each one — from

choosing color swatches (Swatches panel), to

access-ing and editaccess-ing masks (Masks panel), to customizaccess-ing

brushes (Brush panel), to editing layers (the

indispens-able Layers panel) Step-by-step instructions for using

most of the panels are amply provided in other

chap-ters, such as how to monitor clone sources by using

the Clone Source panel in Chapter 14, and how to style

type by using the Character and Paragraph panels in

Chapter 20 In some cases, a whole chapter is devoted

to the mechanics of using a particular panel, such as

the Layers panel in Chapter 8 and the History panel in

Chapter 10

You can read through this chapter with or without

glancing at or fiddling with the panels onscreen, and

also use it as a reference guide as you work The panel

icons are shown on the next page to help you identify

them quickly Following that, you’ll find instructions

for using the Tools panel and an illustration of the

tools, followed by illustrations and descriptions of the

other panels that are used in this book, in alphabetical

order

CHOOSING VALUES QUICKLY

➤ You can change numerical values quickly on the

Options bar, on many panels (such as Adjustments,

Masks, Layers, Character, and Paragraph), and in some

dialogs by using a scrubby slider: Drag slightly to the

left or right over the option name or icon, as shown

below

➤ To access a pop-up slider (e.g., to choose an Opacity

percentage on the Layers panel) click the arrowhead To

close a slider, click anywhere outside it or press Enter/

Return (If you click an arrowhead to open a slider, you

can press Esc to close it and restore its last setting.)

➤ To change a value incrementally, click in a fi eld in

a panel or dialog, then press the up or down arrow key

102 Chapter 6

A When collapsed, each panel has

a unique icon.

The Photoshop panel icons

Each panel in Photoshop has a unique icon.AIf you

keep the panels collapsed to conserve screen space,

you can identify them by their icons You can also

identify collapsed panels via tool tips The panels are

opened individually via the Window menu (To learn

how to configure the panels, see pages 95–97.)

USING CONTEXT MENUS

When you right-click* in the document window — depending on where you click and which tool is selected — a menu of context-sensitive commands pops up temporarily onscreen Many panel thumb-nails, names, and other features also have context menus.If a command is available on a context menu (or can be executed quickly via a keyboard short-cut), we let you know in our instructions, to spare you from having to trudge up to the main menu bar

This is the context menu for a selection.

This is the context menu for a layer mask

on the Layers panel.

*If your mouse doesn’t have a right-click button, hold down Control and click to open the context menu.

The Photoshop panels illustrated*

Using the Tools panel

The Tools panel, which is illustrated on pages

104–106, contains 60 tools and a handful of

buttons! Believe it or not, by the end of this book,

you’ll be marginally to intimately familiar with

most of them

To display the Tools panel if it’s hidden, choose

Window > Tools To choose a tool, do one of the

following:

➤ If the desired tool is visible on the Tools panel,

click its icon

➤ To cycle through related tools in the same slot,

Alt-click/Option-click the one that’s visible

➤ To choose a hidden tool, click and hold on the

visible tool, then click a tool on the menu

➤ To select a tool quickly, press its designated

letter shortcut (don’t do this if your cursor

is in type) The shortcuts are shown in the

screen captures on the next three pages The

shortcut for each tool is also listed in its tool

tip onscreen If Use Shift Key for Tool Switch is

unchecked in Edit/Photoshop > Preferences >

General, simply press the designated letter to

cycle through related tools in the same slot (for

example, press L to cycle through the three

Lasso tools) With the Use Shift Key for Tool

Switch option checked, you have to press Shift

plus the designated letter

➤ To use (spring-load) a tool temporarily while

another tool is selected, press and hold down

its assigned letter key (see the sidebar at right)

To learn the function of a tool as you’re using it,

read the brief description (tool hint) at the bottom

of the Info panel If you don’t see the tool hint,

choose Panel Options from the Info panel menu,

then check Show Tool Hints (see page 114)

Before using a tool that you’ve selected, you

need to choose settings for it from the Options

bar at the top of your screen For example, for the

Brush tool, you would choose a brush preset, and

choose diameter, hardness, blending mode, opacity

percentage, and other settings If the Options bar

is hidden, you can display it by choosing Window >

Options (see page 100)

The current Options bar settings for each tool remain in effect until you change them, reset the tool, or reset all tools To restore the default set-tings to a tool, right-click the thumbnail on the Tool Preset picker (located at the left end of the Options bar) and choose Reset Tool from the con-text menu.AOr to reset all tools, choose Reset All Tools from the menu, then click OK in the alert dialog

In Edit/Photoshop > Preferences > Cursors, you can control whether the pointer displays as cross-hairs or as the icon of the current tool or, for some tools, as a circle either the size or half the size of the current brush diameter, with or without the crosshairs inside it (see page 392)

SPRING-LOADING YOUR TOOLS

➤ To quickly access a tool and its Options bar settings temporarily without having to actually click the tool on the Tools panel, hold down its

tool happens to be selected but you want to move

a layer, which requires using the Move tool You would hold down the V key, drag in the document window, then release V Or to access the Zoom tool temporarily, you would hold down the Z key

➤ This process is slightly less effi cient if you want

to access a tool that shares a slot with other tools (as most tools do) In this case, the letter shortcut accesses whichever tool happens to be visible on the Tools panel To make this work, you could plan ahead and select the tools that you want to switch back and forth among before using them

A To access these two commands, right-click the Tool Preset picker thumbnail, which is located at the left end of the Options bar.

*The 3D tools, and the 3D, Actions, Animation, Measurement Log, Notes, and Paths panels aren’t illustrated in this chapter because

they aren’t covered in this book.

GETTING INFO ON PHOTOSHOP FEATURES

➤ If you’re unsure what an icon signifi es, what a menu is

called, or what a panel or dialog feature or tool does, you

may get the information you need from the tool tip Let the

pointer hover on the feature in question without clicking

the mouse button, and a tip pops up onscreen (For this to

work, Show Tool Tips must be checked in Edit/Photoshop >

Preferences > Interface.)

➤ Some dialogs (such as Edit > Color Settings) have a

your pointer is currently hovering over

➤ Keep an eye on the Info panel for color breakdown

readouts, document data (e.g fi le size, color profi le,

dimen-sions, resolution), and tool hints (ways to use the currently

selected tool) See page 114
