Using the buttons and Pan Mode:
- Zoom In [+] and Zoom Out [-] with the buttons in the bottom right corner of the interface
- Select the Pan Mode [h] to pan the view to get to other parts of the drawing when zoomed in
Using the scroll-wheel on the mouse:
- Scroll Up and Down to zoom in and out
- Scrolling zooms towards or away from the mouse pointer
Return to the default view by clicking the Fit-button [f] in the bottom right of the interface.
All functions have a keyboard shortcut shown by hovering the button with the mouse as well as in the "Display keyboard shortcuts"-list above the "Save"-button. Shortcuts are referenced in the support pages with "[key]".
