John, I ma going with the assumption that all the buttons grouped together are actions

2: agree

3: don't know, don't think IR frequency, I would guess it would fall under #1, then again they might have split it up and 1= IR DB and 2=IR learnt

8: no idea what you mean

9: looks like

?a |
+++|

just thought of this, how about timers? ?=time +++=actions (but then again it could also be conditionals ? for the variable and +++ for actions (but why greyed out)

10: I agree it is the remote, but I still think that it should be an action. Maybe it is special functions
