One app, three studios. Affinity is a single application with Pixel, Vector, and Layout studios. Switch to the Pixel studio for image editing, compositing, and retouching. There is no separate Photo app to launch.
Single-key tools. Press the key to activate: move tool, selection tools (marquee, lasso, freehand), brush, eraser, crop, clone, text, eyedropper, zoom, and hand tool. The complete single-key list is in the table above.
Layer operations. Cmd+J duplicates the current layer (matching Photoshop), Cmd+E merges down, Cmd+G groups, and Cmd+Shift+G ungroups.
Transform. Cmd+T enters transform mode for the current layer, the same as Photoshop.
Selections. Cmd+D deselects, Cmd+Shift+I inverts the selection, and Cmd+A selects all.
Masks. Creating a mask from a selection and applying or inverting masks each have Command-based shortcuts.
RAW and retouching. The Pixel studio includes RAW develop and liquify tooling for photo work, reached from within the studio.
