One app, three studios. Affinity on Windows is a single application; switch to the Vector studio for the vector toolset. There is no separate Designer app.
Single-key tools. Same bare-key tool activation as Mac, with no Ctrl needed to switch tools.
Layer and object management. Ctrl+G groups and Ctrl+Shift+G ungroups. Stacking order: Ctrl+[ and Ctrl+] for backward and forward, Ctrl+Shift+[ and Ctrl+Shift+] for back and front. Ctrl+D duplicates.
Node editing. The same node tool shortcuts as Mac, with Ctrl as the modifier for command operations.
Artboard and canvas navigation. Artboard switching and fit-to-window shortcuts are in the table above.
