(or at least they I assume they're official API members)
As of 0132:

beginRaw()
breakShape()
createPath()
createReader()
curveTangent()
dataFile()
dataPath()
loadMatrix()
noHint()
parseBoolean()
parseByte()
parseChar()
parseFloat()
parseInt()
saveFile()
savePath()
saveStream()
sketchFile()
sketchPath()

and not sure if start()/stop() should be included, stop() is frequently overriden and
super'd, especially to stop the sound libraries.

and not highlighted, but probably intentional in this case, are the library helper
register*() and unregister*(), mentioned only for completeness

also: endRaw()

great, thanks for the list. in fact this is a list of what's not
documented--the keywords file is auto-generated from the docs, so this will
be a helpful guide on what pages to add.
