Hi PP - Int is short for "Intersection".

It is used to snap on to the intersection between 2 curves (the point where 2 curves cross each other).


There are also some additional helpers for Int, like if you are using "Straight snap" to snap the second point of a line along the x or y axis direction, that "straight snap" line will also be intersected with nearby curves to give additional Int snaps.

Does that make sense?

Let me know if you need more information or some examples.
