Fit and zoom
Use Fit to screen to bring the diagram into view. The + and − buttons zoom in and out; the percentage button resets zoom. You can also use canvas wheel or pinch gestures. On smaller screens some toolbar controls are hidden to leave room for the diagram.
Pan and locate
Drag an empty part of the canvas to pan. Dragging an element can move it in an interactive layout, so start in blank space when you intend to move your viewpoint. Select a row in the Systems or Interactions panel, then use Locate selection when it appears to bring the selection into view.
Use a smaller view
For a large model, select a named view from Layout rather than zooming out until every label is unreadable. The view of everything helps check whether an element is missing from the model or simply outside the chosen view.
On a Confluence page
The inline diagram is for reading. Use its view selector to change perspective, Explore for a full-screen inspection session, or Edit to change saved content. Explore movements are temporary.
Tables beside the canvas
Open the Systems/Interactions panel from the left rail. Drag its edge to make more room for columns, or collapse it to give the diagram more space. Sorting a table changes the displayed rows, not sequence-message order in the saved model.
