Keyboard graph navigation: press N for concepts or E for relations; use arrow keys, Home, and End to move; Enter selects; Shift plus Enter selects and centers; plus and minus zoom; zero fits; Escape clears the selection. Use the visible viewport buttons as alternatives to dragging, wheel, and pinch gestures.
Select a concept
Select any concept, construction junction, or annotated relation by pointer, touch, search, or keyboard.
Construction junctions are diamonds. They show where multiple structures must coexist on the same carrier and satisfy compatibility conditions.
Move selected concept
Single-pointer and keyboard alternatives to dragging. Each activation moves the selected concept one step.
An interaction currently treated as irreducible within established theory. The conventional list is gravitational, electromagnetic, strong, and weak; the Standard Model describes the latter three, with electromagnetic and weak interactions unified electroweakly and QCD forming a separate gauge factor.
No alternate terminology is currently authored for this record.

Interaction class
Current classification
Electromagnetic, weak, strong, and gravitational interactions are conventionally treated as fundamental. The Standard Model contains the electroweak and strong gauge sectors but not gravitation.
