What you'll learn: How to navigate any canvas — zoom, pan, the floating Preview Window, pattern-tile preview, reference images, fill / clear shortcuts, and canvas resize / crop.

---

🎯 Goal: Navigate canvases of any size efficiently.

Action	Shortcut
Zoom in/out continuously	Ctrl+Mouse wheel
Zoom in / out 1 step	Ctrl+= / Ctrl+-
Reset to 100%	Ctrl+0
Zoom to canonical level	Hold Z and press 1-8 for 100%-800%, 9 for 1600%, and 0 for 3200%
Zoom tool	Z ()
Zoom to dragged region	Z then drag
Zoom out (Zoom tool)	Alt+Click

Zoom snaps to canonical levels: 25%, 50%, 75%, 100%, 200%, 300%, 400%, 600%, 800%, 1600%, 3200%

You can pan with any tool active, no need to switch:

• Middle-mouse-drag.
• Spacebar+drag.
• Double-middle-click — instantly resets pan and zoom to fit the canvas.

Scrollbars appear automatically for canvases larger than the viewport. The canvas border (#) outlines the edge of the canvas at any zoom.

🎯 Goal: Use preview and tiling for workflow efficiency.

F4 toggles the Preview Window, a floating, resizable, repositionable secondary view. It runs in one of three modes:

1. Follow — a magnifier that tracks the cursor.
2. Floating Image — a static reference display (e.g., the source you're tracing).
3. Bin Quick Look — hover any drawer slot to see its content full-size in the preview.

Independent zoom and pan inside the preview, plus Alt+Click to color-pick without switching tools. The preview also remembers up to 10 recent images for quick swaps.

View → Pattern Tile Mode (or the tile-mode button in the Advanced Bar) toggles a 3×3 tiled preview (up to 512×512 source). Seams in seamless textures jump out instantly because they appear nine times.

• Grayscale Preview — Ctrl+Alt+Shift+G. Inspect value structure without color distraction.
• Reference Image — Ctrl+R. See Chapter 15.

• Delete — clear (Edit → Clear). Removes the active selection's pixels (or the whole layer if no selection). No prompt.
• Backspace — fill with FG color. Instant, no prompt.
• Shift+Backspace — fill with BG color. Instant.

• Crop tool () — interactive with handles; commit with Enter.
  • Drag handles inward to trim the canvas to the selected region.
  • Drag handles outward past a canvas edge to grow the canvas in that direction — new pixels are transparent on all layers. This is a quick alternative to the canvas resize dialog when you just need to add space on one side.
  • Arrow keys nudge the crop box 1px; Shift+Arrow nudges 10px.
• Image → Canvas Resize… — dialog with anchor selection and pixel/percent toggle.
