Starting a new thread because it is new issue.
Updating should make both this and the overprint/overlayarea stuff work. I added some shortcuts for them and other beamer commands in the "Insert Environment/ Insert Command" dictionary.
After updating, I checked the configuration file via LaTeX → Edit Configuration File and could not find these. I then checked /Library/ Application Support/TextMate/Bundles/Latex.tmbundle/Support/ latex.config, and the changes were there, but have no effect---the shortcuts do not work. In the past I have edited the configuration file through the LaTeX bundle (I added support for the quote environment which I use often). Does this mean that editing the configuration file in this way somehow blocks the changes made to / Library/Application Support/TextMate/Bundles/Latex.tmbundle/Support/ latex.config? Or am I doing something stupid? (Likely, I am afraid)
Best, Mark
