It's a variable (even though it may be listed as a constant in some
documentation.) The reader macro #& - followed by the case-sensitive
name of the foreign variable - can be used to access foreign variables:
#<NS-MUTABLE-STRING "NSFont" (#x7FFF701D8410)>
The header file that declares it -
/* Predefined character attributes for text. If the key is not in the dictionary, then use the default values as described below.
APPKIT_EXTERN NSString *NSFontAttributeName; // NSFont, default Helvetica 12
along with declarations for other NSString variables that name character
attributes. It's kind of strange to see something declared as a variable
(an instance of NSString) described as a constant, but it's also hard
to see how how any ObjC instance (of NSString or anything else) is a
"constant" in the same sense that a number or even a C string is.
This is a FAQ.
