Yoshizawa-Randlett System

• Valley fold: fold .a along --b (Works similar for axioms 2-7)
• Mountain fold: Multiple ways, to be specified [*]
• Fold and unfold: @fold .a over --b
• Turn over: flip
• Rotate: rotate 90 or rotate 90°
• Put the points together: fold .a to .b
• Inside crimp fold: ...
• Outside crimp fold: ...
• Inside reverse fold: ...
• Outside reverse fold: ...

[*]
So far I thought a good way to differentiate between valley and mountain folds is to default to valley, but allow an explicit mountain fold .... This is still viable for axioms 2-7, but the wording for axiom 1 sounds off. mountain fold .a over --b should be fold .a under --b. That however breaks consistency.

fold .a along --b and mountain fold .a along --b?
