Interface zones
| Zone | Location | What it holds |
|---|
| Toolbar | Left edge | Creation, 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 bar | Top edge, below menu bar | Context-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 / palettes | Right side | Layers, 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. |
| Canvas | Center | The 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 bar | Bottom of canvas | Document 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:
| Preference | Setting | Why |
|---|
| Performance → Memory Usage | Set to 70–80% of available RAM | Photoshop is memory-intensive. More RAM allocated = faster operations on large files. |
| Performance → GPU Settings | Enable OpenCL if available | Enables GPU-accelerated features including some filters and the Scrubby Zoom. |
| Performance → History States | 60–100 states | The undo stack depth. More states = more undo steps but higher memory use. |
| Cursors → Painting Cursors | Normal Brush Tip, Show Crosshair | Shows the actual brush size and a center crosshair — essential for precise brush work. |
| File Handling → Autosave Recovery | Every 10 minutes | Photoshop 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.
