Meaning of という when it doesn't mean 'call', 'be called', or 'say'


I'm having a little trouble parsing the usage of 「という」 when it it has meanings
other than `to call`, `to be called` or `to say`.

I often see sentences like 「いざという時, ということだ」 and 「これという問題はない」. The dictionary I
use gives the definition: `とりたてて言う意を表す。` But I'm still quite unsure about it.
If someone could explain how that definition fits into those uses then I'd be
grateful.




という actually has multiple meanings. This part of Tae Kim's Guide should be a
good read for you: <http://www.guidetojapanese.org/learn/grammar/define>
