Besides a matter of taste, the marked text (corresponding to preedit
in XIM) is not necessarily identical to the pressed key (e.g.,
Japanese input methods).

They are in the Cocoa NSTextInput terminology.  The "marked text"
corresponds to "preedit" in XIM as above or "active input" in Carbon
TSM.  I don't know why the Cocoa/GNUstep port call it "working text".
The "selected range" represents the caret position in the marked text.
