Kenwood VR-509 Remote

[ElementZ]

Yo, i got the kenwood reciever VR-509, i think its a pretty dope reciever. Anyways, it comes with a universal learning remote which can learn, has macros, RF, and an LCD screen in it. For the TV and DVD menus that it has built inside, im not sure what some of the options mean, even when i press them they dont do anything but i would still like to know what they are there for.
Hopefully somebody will know them or could at least guess them or direct me to a website which might explain them, of course the manual dosent.

TV

1) -/--
2) >12
3) Wide
4) P in P (this one is obvious)
5) Text ( i thought these two would mean close caption but nuthin comes up
6) Text off
7) Mix
8) Exit

CD/DVD

1) Disc Sel (i know this)
2) Chp/Time (self explanatory)
3) Angle ( i know this one)
4) PGM
5) DVD Set
6) Memory
7) Clear
8) Repeat AB ( know it)
9) Sub Titl ( know it)
10) T. Search
11) Disc Title
12) Track Title
13) All Read
14) Aspect
