Some interesting Emacs threads and LaTeX news

C K Kashyap posited some new requirements on code folding and there were a number of interesting responses culminating with a link to HideRegion.  You probably should stick to hide-show or OutlineMode and venture into these solutions only if there is a use case that is not met by hide-show. :)

Did you forget to enable auto-fill while writing text?  No worries, you can fix the written text with a simple C-x h M-q .

Have some file and project management stuff that you want Emacs to handle?  Here's a thread on what one user would like to see as project management that he wants emacs to do some heavy lifting. Might be worth your time to check it out.

BTW, there's a new site pgfplots.net for fantastic LaTeX plotting by the LaTeX guru Stefan Kottwitz.  You should check it out and contribute your pgfplots to it.

Incrementing counters in Emacs macros

If you've used macros in Emacs, sooner or later you'd need to automatically increment as expressed in this thread. If you read the thread, you'd see a number of suggestions but the simplest is to use the builtin Emacs counters. The Emacs manual too mentions how to use them.

The Emacswiki too mentions how to use them and some tricks in getting it to do it the way you want.

Learn it, it saves a tremendous amount of drudgery typing

Emacs command equivalents for Vi users

On the gnu.emacs.help newsgroup, there is this thread on Emacs equivalent of some vi commands.  The poster had helpfully created a emacswiki page called ViEmacsTable and listed some of the answers he received.

Well, I've just edited it to add some equivalents that I think are the closest to vi's commands.  Feel free to correct them if they're in error and add anything that you think might be useful.
