Re: [ jEdit-users ] Can't use Alt key in jEdit 5 under Mac OS X

[Advrk A. <avk...@gm...>]

Interesting...
No my Emacs does not use X, it was built via MacPorts and directly
uses Mac OS X 10.6.8's Aqua interface.
I tried some Alt key combinations in other software and yes that also
produces symbols. Looks like Emacs does something to prevent this???
