[Openmcl-devel] Two quick questions

[Ron Garret]

I can probably figure these out myself, but I thought I'd see if  
anyone knew the answer offhand before I spent a lot of time on this.

1.  What is the difference between marked and selected text in an  
NSTextInput object?

2.  Is there in the Hemlock code somewhere (or anywhere else) a  
function that, given a string and an index of a close-paren within  
that string will return the index of the corresponding open-paren?   
It's easy to write a naive version of this, not so easy to write one  
that correctly handles all Lisp syntax, including strings, escape  
characters and reader macros.

Thanks,
