Keyboard
Keyboard operations are heavily dependent on the focus: which part of the application is currently active. Most of the time the drawing canvas is the active part and handles keyboard operations. However, if some tool dialog is active, all key presses go to it. Programs tries to switch focus automatically to the relevant part of the application, but sometimes it will be necessary to activate canvas or dialog focus by clicking it with the mouse.
Keyboard shortcuts for menu commands usually work always regardless of the current focus.
