Not only that, you can have a place holder that starts with •‹ and ends with › surrounding a comment so you can add a short memory jogger (note: ‹ and › are NOT < and > but open/close single guillemet quotes). When you jump to a comment the complete comment is selected. Finally, AutoComplete in TeXshop retains indentation for those that like to ``pretty print'' environments. PS: that file MUST be saved in UTF-8 Unicode since it uses non-ascii characters and is read in by TeXShop as UTF-8.

There is a final • at the end of many commands if it would require multiple keystrokes to get to the end; especially true of environments but also true of several commands. You get to each of the • by pressing the Tab key (Shift-Tab to go backwards) in TeXworks.

I was thinking that in for example


you end up with the cursor on the same line as you started but


leaves the cursor on a different line. On the other hand, it's probably
more convenient to have the cursor at the position of the first 'fill
in' point rather than having in some cases to go backward as well as

Having thought about it some more, the current behaviour is almost
certainly the best default.

This has been `fixed' in TeXShop by allowing two #INS# commands and everything in between is selected. So, in TeXShop, the first argument is set at #INS#•#INS#.

Yes, the TeXShop plan does sound sensible :-)

The reason I mentioned this is that it's common to lay out input in the form

    Content of foo
  more content

i.e. with the \begin/\end statements on lines of their own. Of course,
not everyone does this.

I guess I'll just fiddle about with my own autocomplete files :-)
