Emacs on MacOS
The native Emacs seemed not to have a meta key. While this might be fine for amateurs, it is definitely not fine for hard-core Emacs users. The lack of meta seemed to be the case irrespective of whether it was under MacOS or under X11. I kept tweaking my .Xmodmap to no avail.
The general advice on the net was to install 22.1 using MacPorts. So I went down that path. MacPorts installed, though it required XTools, which was a bit of a pig. Then I build 22.1. It did not seem to support the meta key!
A co-worker who was also at the APNIC meeting in Taipei said just install Carbon Emacs. So I Googled it and installed it, and it worked under X11 and native MacOs.
Of course, now i want to rip out MacTools etc., but am not sure how to do so safely.
