Save a component

Keep this geometry, its formulas, and its internal relationships in the presentation library.

One item per line. Indent branches with spaces.

The presentation is a model of geometry, bindings, and constraints. Drag objects or their handles; attached geometry updates from those relationships.

Fast flows

Select a node and drag a yellow port to another object. Drop on empty canvas to create a connected node. Tab creates the next node and Shift+Enter creates a branch.

Slides + themes

Use Slides to add, duplicate, reorder, and present pages. Theme colors update linked objects across the document; individual objects can keep overrides.

Selection + assemblies

Drag a box on empty space. Left-to-right selects enclosed objects; right-to-left selects intersecting bounds. Shift adds to selection. Group with ⌘/Ctrl G.

Arrange + style

Align edges or centres, distribute equal gaps, run Auto layout, and adjust named styles or individual colors.

Connected copies

Copy, paste, and duplicate keep selected objects connected to their original references. In Properties, choose Copy references for an independent construction or Detach external links for a free copy. Pasting onto another slide includes the required references.

Precision + connections

Properties shows incoming rules, reference names, and followers. Reconnect, pause, or detach a rule. Move and scale with exact values, repeat copies with an offset, or nudge using arrow keys (Shift: 10 units, Alt: 0.1).

Move + resize

Select an object, then drag its centre or square handles. Alt temporarily bypasses snapping. Locked or constrained geometry keeps its rules.

Save + export

Save project retains every slide, theme, editable object, binding, and constraint. Export the current slide to SVG/PNG or the complete deck to PPTX.

Signal is a constructive 2D presentation editor. Its geometry and relationships remain the source of truth for every export.
