Hotkey Reference

This page summarizes support-placement hotkey behavior.

Precedence

When modifiers overlap, more specific combinations win:

1. Ctrl+Alt → Leaf family
2. Alt → Branch/Brace family
3. Ctrl → Kickstand family
4. No modifier → Default trunk placement

Key press order does not matter.

Support placement rules

• Alt plus a model-first click enters the branch flow.
• Alt plus a support-first click enters the brace flow.
• Ctrl plus a support-first click enters kickstand placement.
• Ctrl+Alt always owns the interaction for leaf placement when the first valid click is on the model.

Resolution matrix

No modifier

• First click on model → default trunk/root placement.

Alt held

• First click target decides the placement family:
• First click on model → branch-family flow.
  • Second click on support shaft → Branch.
  • Second click on model → Twig or Stick.
• First click on support shaft → brace-family flow.
  • Second support click → Brace.

Ctrl held

• First click on support shaft → Kickstand.

Ctrl+Alt held

• First click on model → Leaf flow.
• Second click on support shaft → Leaf.

Cancellation rules

• Releasing a required modifier key cancels the active placement family.
• Canceling clears preview/snap/hover transient state.
• Re-entering starts from a fresh state (no stale preview resurrection).

Explicitly forbidden outcomes

• Ctrl+Alt should never fall through to kickstand or Alt-only branch behavior.
• Key order must not change the final result when the held modifiers are the same.
• Re-entering placement must not resurrect stale preview state.

Quick cheat sheet

• Alt + model first → Branch/Twig/Stick
• Alt + support first → Brace
• Ctrl + support first → Kickstand
• Ctrl+Alt + model first → Leaf
