Interface, Preferences, and Navigation

Photoshop's interface adapts to what you're doing. Understand what each zone does and how to reach any tool without hunting for it.

Interface zones

ZoneLocationWhat it holds
ToolbarLeft edgeCreation, selection, retouching, and view tools. Many buttons have hidden sub-tools — click and hold to reveal them. The active sub-tool is what keyboard shortcuts activate.
Options barTop edge, below menu barContext-sensitive options for the active tool. Changes completely when you switch tools. Read it before using any tool — it controls behavior you can't control elsewhere.
Panels / palettesRight sideLayers, Channels, Properties, Adjustments, Color, Swatches, and others. Window menu opens any panel. Panels can be grouped, separated, and docked. Customize your workspace and save it — don't reset to default every session.
CanvasCenterThe active document. Grey area around it is the pasteboard — content can extend beyond the canvas boundary without being cropped, but won't appear in exports.
Status barBottom of canvasDocument size, zoom level, and other document info. Click the arrow to change what's displayed.

Key preferences to set

Photoshop → Preferences (Mac) or Edit → Preferences (Windows). The settings below are the ones most likely to affect your workflow:

PreferenceSettingWhy
Performance → Memory UsageSet to 70–80% of available RAMPhotoshop is memory-intensive. More RAM allocated = faster operations on large files.
Performance → GPU SettingsEnable OpenCL if availableEnables GPU-accelerated features including some filters and the Scrubby Zoom.
Performance → History States60–100 statesThe undo stack depth. More states = more undo steps but higher memory use.
Cursors → Painting CursorsNormal Brush Tip, Show CrosshairShows the actual brush size and a center crosshair — essential for precise brush work.
File Handling → Autosave RecoveryEvery 10 minutesPhotoshop crashes. Autosave is insurance, not a substitute for manual saving.

What breaks

Sub-tool state not matching expectation — if a keyboard shortcut produces the wrong tool behavior, the sub-tool is set to a variant you didn't intend. Check the toolbar icon for the small arrow indicating sub-tools, and click-hold to see which variant is active.

Panels closed and no way to find them — all panels are accessible through the Window menu. If your workspace looks wrong, Window → Workspace → Reset [workspace name] restores the saved state.
