Panning and Zooming

The canvas is effectively infinite, so diagrams are never cramped. Panning moves your view across the surface, and zooming changes how much of it you see at once. There are several ways to do each, so you can use whichever suits your device.

Panning

Panning slides the canvas under your view without moving any elements.

• Hand tool. Pick the Hand tool from the palette (shortcut H), then drag on empty canvas to scroll around. It is the default tool on touch devices.
• Middle-click drag. A middle-mouse-button drag pans from any tool, so you do not have to switch away from Select to move around.
• Hold Space. Holding Space and dragging pans while keeping your current tool, which is handy mid-edit.
• Two-finger trackpad. A two-finger gesture pans on a trackpad.

When you pan, background patterns track the pan offset and tile seamlessly, so the texture stays continuous however far you travel.

Zooming

Use the on-screen zoom controls to scale the view in and out. Zooming in lets you place and label small elements precisely; zooming out gives you the whole diagram at a glance, which is useful before presenting or when tidying up a large layout.

Presenter aids

When you are walking others through a diagram, a couple of canvas tools help direct attention without changing the layout.

• Laser emits a glowing trail that follows your pointer and fades after about a second, broadcast live to collaborators in your colour.
• Spotlight dims the whole canvas except a soft circle around your cursor, a local view aid that draws the eye to one area. Left-click grows the light, right-click shrinks it.
