[Interest] [osx] cmd-period mapping

thanks a lot for the explanation. however there is one thing, that i
don't quite understand: cmd-. on a QPlainTextEdit adds a . to the
document ... so it is not completely swallowed by cocoa ... also i
wonder, why the hell qt doesn't post a run-time warning when setting
cmd-. a shortcut, especially as qt4 did handle the case ...

iac, i think i can hack my way around it, now ...
