The Canvas tab of a project is the node editor, and it behaves like a drawing surface rather than a form.
### Moving around
- Scroll (or pinch) zooms around the cursor. + / − and 0 on the keyboard zoom in, out and reset.
- Space + drag, Alt + drag or the middle mouse button pans. The minimap in the corner shows where you are; click it to jump.
- F fits everything into view.
- Below about 55% zoom nodes draw as labelled blocks with no ports or settings — that is deliberate level of detail, so a hundred-node graph reads as a shape.
### Selecting and arranging
- Drag on empty canvas to marquee-select; Shift + click adds to the selection. Ctrl/⌘ + A selects all.
- Dragging snaps to the grid and to other nodes' edges (a guide line appears). Turn snap off in the toolbar.
- G groups the selection into a named frame; Shift + G ungroups. Groups are saved with the graph.
- D duplicates, Delete removes, arrow keys nudge (Shift for a whole grid step).
### Bookmarks and tabs
- Bookmark a view (name it, or press B) and jump back with 1–9. Bookmarks belong to the saved canvas.
- Tabs hold several canvases in memory — open a saved one from the list, or start a new tab from a template — and only the one you save reaches the server.
Press ? on the canvas for the shortcut list.
