The tutorial at http://arduino.cc/en/Hacking/LibraryTutorial says to create a file called keywords.txt in the new library's directory so that the keywords are highlighted in color. However, placing the keywords.txt file in the library's folder and even adding the file from the IDE doesn't work. The keywords still aren't highlighted. What seems to be the problem?
The function name and the "KEYWORD" must have a single tab space ( or 4 spacebar presses) between them. NOTE the spaces will not all look the same, but if you know you pressed tab once, then save it, the function names will be in color.
Example:
Somefunct KEYWORD1
