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.

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.
