What did you mean by "testing"?
I take it back. I had both a "mouseWithin" and a "mouseEnter" handler in the
same script, just fooling around. When I comment out the "mouseEnter", the
"mouseWithin" is not sent. And this is spelled out in the dictionary. Well what
do you know?

Like most languages, LiveCode provides a way to express the bounding
rectangle of an object, as well as its location.
But it may be helpful to note that these values may be different from
what you'll find in other languages.
For example, in JavaScript/CSS, the order of rectangle coordinates is:
top, right, bottom, left
...but in LiveCode (and other xTalks) the order is:
left, top, right, bottom
Also, in some other languages the location property is a pair of
coordinates expressing the top-left of the object, but in xTalks like
LiveCode the location is the centerpoint of the object. Thankfully both
languages use the same order for points, x,y.
Possibly beyond the scope of your interest, if you're coming from a CSS
background it can be helpful to remember that the margin property in LC
is the opposite how it's used in CSS: in CSS the margin defines the area
outside of the control's border, but in LiveCode is defines the boundary
within the border (such as the space between the edge of a field and the
text within it).
In LiveCode you can observe and modify the size and location properties
of selected controls with the "Size and Position" pane of the Inspector.
