Add keywords to IDE

Hi folks,

I would like to add some keywords to the IDE's syntax highlighting. I've found /usr/share/arduino/lib/keywords.txt but I prefer to experiment on user files as opposed to system files whenever I can. (Yes, I know I can do backup copies, work with soft links and so on, but still.) Does the IDE look for config files in the home tree at all? All I could find is ~/.arduino/preferences.txt

"man arduino" (Debian version) didn't help at all, by the way.

My version of the IDE is 1.0.5. Perhaps newer versions work differently?

Create a dummy library folder and add a file named keywords.txt to it. Look at the existing library keywords files to see the layout and contents.
