Serveral operators missing in language reference

Several operators i (frequently) use are missing from the reference page:
arduino.cc/en/Reference/HomePage

The ones that are missing:
-Modulo assignment %=
-Bitwise XOR assignment ^=
-Bitwise left shift assignment <<=
-Bitwise right shift assignment >>=

Is there any reason why they where left out? Perhaps to prevent confusion amongst beginners? Well, this incompleteness did confuse me a little.

Also, just something i noticed. The increment and decrement operators are listed under the compound asignment operators, but in the wikipedia article they are listed under the Arithmetic operators.

As far as I can tell, all of those are there on the page:

http://arduino.cc/en/Reference/HomePage

Modulo (%) is listed under "Arithmetic Operators", while the others (XOR, left/right shift) are listed under "Bitwise Operators".

As far as the differences between the Wikipedia article and the Arduino reference, chalk it up to differences in labeling and semantics...

No, s/he is quite correct, the [u]compound[/u] operators listed in the OP are not on the page you linked.

I just found out where it was hidden all along. You have to click through to get to the Bit Math Tutorial and scroll down. I prefer shortcuts of operators close to the operators themselves.
