Sounds like a cool project! The I beam is called the "insertion point" in 
NSTextView. You can get the character index of it using

[self selectedRange]

inside NSTextView. The I-beam is only present if length == 0 and location != 
NSNotFound.


To get the (x,y) coordinates for positioning the popup window, you can use 
-firstRectForCharacterRange:. (NSTextInput protocol). Note that apple's docs 
say this returns a result in screen coordinates, but our NSTextView's 
implementation doesn't seem to do that.
