In addition to the menu shortcuts seen in the menus themselves there are further convenient key bindings defined to directly invoke certain actions.
The following shortcuts are available in the Search field of the Structure View, if it has the focus.
Besides the "normal" gestures possible within the drawing canvas, like, e.g., creating a node with a simple mouse-click, direct control of canvas features is also provided.
Using the mouse wheel it is possible to zoom in and out of the drawing canvas. By default, the canvas's area is centered at the current mouse position.
The current viewport (the visible diagram area) of the editor window can be changed by right-dragging the mouse around. The viewport will follow the mouse.
If you switched to Navigation Mode, then you can also move the viewport with the left mouse button.
