ptg Workspaces 93 When you have multiple documents open (say, in a 2-Up or 3-Up layout), you can save time by scrolling or zooming all of them simultaneously. To scroll or zoom in multiple windows: 1. Open two or more documents, then on the Arrange Documents menu, click a 2-Up, 3-Up, 4-Up, 5-Up, or 6-Up icon. 2. Do either of the following: To scroll or zoom all the open Photoshop docu- ment windows, hold down Shift while using the Hand or Zoom tool. Check Scroll All Windows on the Options bar before using the Hand tool, or check Zoom All Windows on the Options bar before using the Zoom tool. Rotating the canvas view OpenGL is a cross-platform API (application pro- gramming interface), or language, that was devel- oped by Silicon Graphics for 2D and 3D computer graphics applications. To use the OpenGL features in Photoshop, such as Animated Zoom (see the Note on page 91), Scrubby Zoom, ick panning (see the last tip on the preceding page), or the Rotate View tool (discussed below), your system must con- tain a video driver or card that provides OpenGL acceleration. To enable OpenGL drawing in Photoshop, go to Edit/Photoshop > Preferences > Performance, then under GPU Settings, check Enable OpenGL Drawing. Relaunch Photoshop. Unlike the Image > Image Rotation commands, which rotate the image permanently, the Rotate View tool tilts the canvas temporarily so you can draw or paint at a particular angle. To rotate the canvas view by using the Rotate View tool: 1. Choose the Rotate View tool (R), or hold down R to spring-load the tool. 2. Do either of the following: Drag in the image. A On the Options bar, enter a Rotation Angle value, use the scrubby slider, or move the dial. To reset the canvas to the default angle: 1. Choose the Rotate View tool (R). 2. Click Reset View on the Options bar. A With the Rotate View tool, drag to tilt the canvas area temporarily. ptg 94 Chapter 5 Changing the screen mode e three screen modes control which Photoshop interface features are displayed onscreen. To change the screen mode: Press F to cycle through the screen modes, or from the Screen Mode menu on the Application bar, A choose one of the following: Standard Screen Mode (the default mode) to display the Application frame (if turned on), document tabs, the Photoshop menu bar, Application bar, Options bar, and panels — with the Desktop visible behind everything. Full Screen Mode with Menu Bar to display the current document on a full-screen gray (default color) background, obscuring the Desktop, with all of the above-mentioned interface features showing. B Full Screen Mode to display the current docu- ment on a black (default color) background, with the Photoshop interface features and Desktop hidden and the panels visible only upon rollover (see “To make hidden panel docks reappear” on the next page). ➤ When color accuracy is important to us (which, come to think of it, is all the time!), we like to keep the area around the image gray. If you want to change the color of the area around the image for just the current screen mode, right-click that area and choose Gray, Black, or Custom (the last chosen custom color) from the context menu, or choose Select Custom Color and choose a color from the picker. You can also change the color around the image for any or all of the three screen modes via the Preferences dialog; see page 388. B When performing color correction work, we choose Full Screen Mode with Menu Bar as the screen mode for Photoshop. Choosing a predefined workspace e quickest way to change your panel setup is by choosing a predened workspace. ey’re designed for dierent kinds of tasks. (To create and save custom workspaces, see pages 98–99.) To choose a predefined workspace: ★ On the Application bar in Photoshop, do either of the following: Click a workspace name, such as New in CS5, Design, Photography, Essentials, or Painting. C Choose a workspace from the Workspace menu on the Application bar. ➤ To display more workspace names on the bar, drag the vertical gripper bar to the left. A Choose an option from the Screen Mode menu on the Application bar. Drag this bar to the left to reveal more workspace names. C To quickly change your panel setup, click a workspace name on the Application bar. ptg Workspaces 95 Configuring the panels When you need to fully maximize your screen space, you can hide all the currently open panels and easily make them reappear only when needed. To hide (or show) the panels: Do either of the following: Press Tab to hide (or show) all currently open panels, including the Tools panel. Press Shift-Tab to hide (or show) all currently open panels except the Tools panel. ➤ To open a panel individually, choose the panel name from the Window menu. To make hidden panel docks reappear: 1. Hide the panels as just described or choose Full Screen Mode from the Screen Mode menu on the Application bar. 2. If the document is in Standard Screen mode, let the pointer pause on the dark gray vertical bar at the right edge of the Application frame; or if your document is in either one of the Full Screen modes, let it pause at the edge of your monitor. A e panel docks will redisplay temporarily (but freestanding panels will remain hidden). B Move the pointer away from the panels, and they’ll dis- appear again. Note: If this mechanism doesn’t appear to be working, right-click any panel tab or icon and choose Auto-Show Hidden Panels from the context menu. at should do the trick. ➤ If you prefer to keep your panels visible onscreen but want to minimize how much space they occupy, shrink them to icons (see the last para- graph on the next page). A With the panels hidden, if you let the pointer pause on the dark vertical bar at the right edge of the monitor or Application frame… B …the panel docks will reappear temporarily. If you move the pointer away from the panels, they’ll disappear again. ptg 96 Chapter 5 Most of the edits that you will make in Photoshop will require the use of one panel or another. A clever interface makes the panels easy to store, expand, and collapse so they don’t intrude on the document space when you’re not using them. Note: e indi- vidual panels are illustrated in the next chapter. In the predened workspaces (which are accessed via the Application bar), the panels are arranged in docks on the right side of your screen — except for the Tools panel, which is on the left side. Each dock can hold one or more panels or panel groups. A In this section, we’ll show you how to recongure them. To reconfigure the panel groups and docks: Open or close a panel: Open a panel by choosing its name from the Window menu (a few panels can also be opened or closed via a keyboard shortcut, which is also listed on the menu). e panel will display either in its default group and dock or in its last location. To bring a panel to the front of its group, click its tab (panel name). Expand a panel that’s collapsed to an icon: Click the icon or panel name. If Auto-Collapse Iconic Panels is checked in Edit/Photoshop > Preferences > Interface and you open a panel from an icon, it collapses back to the icon when you click elsewhere. With this preference unchecked, the panel stays expanded; to collapse it back to an icon, you must click either the Collapse to Icons button on the panel bar or the panel icon in the dock. ➤ To quickly access the Auto-Collapse Iconic Panels option from a context menu, right-click any panel tab, bar, or icon. Maximize or minimize an expanded panel or group vertically (to toggle the full panel to just a panel tab, or vice versa): Double-click the panel tab or title bar (the gray bar next to the panel tabs). Use a panel menu: Click the icon to access the menu for whichever panel is in front within its group. Close a panel or group: To close a panel, right-click the panel tab and choose Close from the context menu. To close a whole panel group, choose Close Tab Group from the same context menu. Collapse a whole dock to either icons or icons with names: Click the Collapse to Icons button at the top of the dock, or double-click the dark horizontal gray bar. B To expand icons to icons with names, or vice versa, drag the vertical edge of the dock horizontally. C A  e s e a r e t h e t w o p a n e l docks in the predened Photography workspace. In the left dock, panels are collapsed to icons with names; in the right dock, they’re organized in three groups. e Layers/ Channels/Paths group is minimized vertically. B We clicked the Collapse to Icons button to shrink the rightmost dock to icons. e panel groups were preserved. C We dragged the edge of the left dock inward to shrink the dock to just icons (no names). ptg Workspaces 97 Widen or narrow a dock and panels: Position the pointer over the vertical edge of the dock ( cursor), then drag horizontally. Lengthen or shorten a panel or group: Position the pointer over the bottom edge of the panel or group, and when you see this pointer, drag upward or downward. Panels docked in the same group will resize accordingly. Note that some panels can’t be lengthened or shortened. Move a panel to a different group: Drag the panel tab over the title bar of the desired group, and release when the blue drop zone border appears. A Move a panel to a different slot in the same group: Drag the panel tab (name) to the left or right. Move a panel group upward or downward in a dock: Drag the title bar, then release it when the horizontal blue drop zone bar is in the desired location. B Create a new dock: Drag a panel tab or title bar side- ways to the vertical edge of the dock, C and release the mouse when the blue vertical drop zone bar appears. Reconfigure a dock that’s collapsed to icons: Use methods similar to those for an expanded group. Drag the group “title” bar (the double dotted line) to the edge of a dock to create a new dock; or drag the title bar vertically between groups to restack it (look for a horizontal drop zone line); or drag the title bar into another group to add it to that group (look for a blue drop zone border). Make a docked panel or group into a floating one: Drag the panel tab, icon, or title bar out of the dock. To stack oating panels or groups, drag the top bar of one to the bottom of another. Resize a floating panel: Drag the resize box (located in the lower right corner) inward or outward, or drag the right edge of the panel horizontally. To resize the Adjustments panel, click the Expanded View button. Not all panels are resizable. ➤ To keep a oating panel from docking while it’s being moved, hold down Ctrl/Cmd. To redock floating panels into the Application frame: Drag the dark gray bar at the top of the panel group to the right edge of the Application frame, and release the mouse when the pointer is at the edge of the frame and a vertical blue drop zone line appears. ➤ For any tool that uses a brush, you can show the Brush panel by clicking the Toggle Brush Panel button on the Options bar or Brush Presets panel. ★ For the Type tool, you can show the Character panel by clicking this button: . C A blue vertical drop zone bar appears as we drag the History panel out of a dock to create a new dock for it. B A blue hori- zontal drop zone bar appears as we move our Channels/Layers panel group upward within the same dock. A A blue drop zone border appears as we drag a panel into a dierent group. ptg 98 Chapter 5 B In the New Workspace dialog, enter a Name for your workspace and check either or both of the optional features. 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 dierent kinds of tasks. is will shorten your setup time when you begin your work sessions. A In 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 reect 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.
