I'm working on an application in which users enter data into a

this list, I'm not much closer to determining the best way to do
this (or even how to do it). So far, I have been thinking I have to
do something with NSWindow and the fieldEditor; perhaps setting the
window's field editor to be a particular NSTextView, and implement
some method in that text view (insertText:?) to make the
substitution. I take it that working with keyDown: would not be the
best approach. Would this be on the right track? Any help would be
appreciated.
You could try adding a validate<Key> method for the property that
holds the string value. In that method, take the input string and
create a new string, replacing whatever characters you need to. Pass
the new string back in the first parameter, and return YES from the
method.
If I haven't overlooked something obvious, this would work no matter
whether the text was typed or pasted into the editing field.
Oh -- make sure you check "Validates immediately" for the table column
binding in IB, too.
