+ Input basics and modifiers
+ -
+
- Left click uses Color 1; right click uses Color 2 for drawing, fills, shapes, and picking. +
- Middle mouse drag pans the viewport when anchored; in free mode it drags the canvas itself. +
- Ctrl + mouse wheel zooms the view; with the Zoom tool active, zoom always follows the cursor. +
- Mouse wheel without Ctrl scrolls the viewport. +
+
+ Canvas, zoom, and anchoring
+ -
+
- Anchor locks the canvas to the viewport; free mode lets the canvas float and be dragged. +
- Center recenters the view without changing pixels. +
- Zoom tool: left click zooms in, right click zooms out. +
- Resize handles on the right, bottom, and corner are always visible; left/top handles appear in free mode. +
- Dragging a resize handle previews the new size; releasing commits the resize and shifts pixels if needed. +
- When anchored and the Zoom tool is not active, Ctrl + wheel keeps the top-left corner steady. +
+
+ Selections and modifiers
+ -
+
- Drag with Select to create a marquee; Shift constrains it to a square. +
- Drag inside a selection to move; Ctrl-click inside stamps a copy before moving. +
- Shift while moving a selection stamps repeatedly as you drag. +
- Selection handles resize from the opposite anchor corner. +
- Shift adds, Ctrl subtracts, Alt intersects for Lasso and Wand selections. +
- Cancel Selection restores the selection to its original position. +
+
+ Lasso select
+ -
+
- Click to start a polygon; click again to add points. +
- Free-form: click-drag to draw; release to finish. +
- Polyline: click to add points; Enter or double-click to finish. +
- Lasso inherits selection modifiers: Shift add, Ctrl subtract, Alt intersect. +
+
+ Magic Wand
+ -
+
- Click to start; drag away from the start point to increase tolerance (distance controls it). +
- Release to finalize the selection using the current tolerance. +
- The tolerance slider steps in 0.5 increments. +
- Contiguous selects only connected pixels; Global selects matching pixels everywhere. +
- Wand also supports Shift add, Ctrl subtract, Alt intersect. +
+
+ Pencil, eraser, fill, and picker
+ -
+
- Pencil draws pixel-perfect strokes; Ctrl locks to the dominant horizontal or vertical axis. +
- Eraser uses its size; right click runs color-replace along the stroke. +
- Fill floods a connected region with the active color. +
- Picker samples a pixel into Color 1 (or Color 2 with right click) and returns to the last draw tool. +
+
+ Lines, shapes, polyline, curve
+ -
+
- Rectangle/Circle/Triangle: drag to size; Ctrl draws from center with equal width/height. +
- Line: Ctrl snaps to vertical/horizontal/diagonal; Shift snaps to 45-degree angles. +
- Polyline: click to add points; Ctrl closes to the first point; Enter or double-click commits. +
- Curve: click start, click end (Ctrl constrains), click control 1, click control 2 to commit. +
- Shape previews live on the temp layer until committed. +
+
+ Selections menu actions
+ -
+
- Select All, Invert Selection, and Delete are available in the Select menu. +
- Crop applies the active selection as the new canvas bounds. +
- Transparent Selection toggles keyed transparency in selection previews and pasted content. +
+
+ Hue/Sat and adjustment dialogs
+ -
+
- Hue/Sat operates per channel; Split View shows before/after with a draggable divider. +
- Cancel restores pixels; OK commits the adjustment. +
- Resize/Skew supports percent or pixels and an optional aspect lock. +
- Decrease Color Depth offers palette or 15/16bpp modes plus optional dithering. +
+
+ Colors, palettes, and swatches
+ -
+
- Left click a swatch sets Color 1; right click sets Color 2. +
- Swap flips Color 1 and Color 2. +
- Edit Colors opens the Win-style color dialog. +
- Palette export/import uses JASC-PAL format. +
+
+ Gridlines and overlays
+ -
+
- Gridlines are a visual overlay only; spacing and color are configurable. +
- The grid stays one screen pixel thick for crispness at any zoom. +
- Selection ants and outlines are previews; pixels are unchanged until committed. +
+
+ Clipboard and paste
+ -
+
- Copy/Cut uses the active selection; Paste creates a floating selection. +
- Paste honors Transparent Selection if enabled. +
+
+ Save, export, and reminders
+ -
+
- Save uses the file handle if available, otherwise downloads a new file. +
- Export supports PNG/JPEG and color profiles (sRGB, Display P3, Adobe RGB, CMYK simulations). +
- Save reminders wait for a short idle gap before showing. +
+
+ Default hotkeys (customizable)
+ -
+
- P Pencil, E Eraser, G Fill, S Select, W Wand, F Rectangle, T Transparent Selection. +
- Ctrl+Z Undo, Ctrl+Y Redo, Ctrl+S Save, Ctrl+O Open, Ctrl+N New. +
