The FAQ should cover them all. Also, the course notes for ApacheCon
2001 should cover them in a little more detail:

Actually, the place you want to look is a little further down in
builtins.c. Those listed above are the function names, but not the
string mappings. This is the code:

static struct cpd BuiltinFuncsTable[_BuiltinCount] = {
{"off", NULL, backhand_off, NULL},
{"byAge", NULL, byAge, NULL},
{"byCost", NULL, byCost, NULL},
{"byLoad", NULL, byLoad, NULL},
{"byBusyChildren", NULL, byLoad, NULL},
{"byCPU", NULL, byCPU, NULL},
{"byLogWindow", NULL, byLogWindow, NULL},
{"byRandom", NULL, byRandom, NULL},
{"removeSelf", NULL, removeSelf, NULL},
{"addSelf", NULL, addSelf, NULL},
{"addPrediction", NULL, addPrediction, NULL},
{"HTTPRedirectToName", NULL, HTTPRedirectToName, NULL},
{"HTTPRedirectToIP", NULL, HTTPRedirectToIP, NULL},
{"bySession", NULL, bySession, NULL}
};

So, "off" is the keyword not backhand_off (that is just the function
name).

So, you are almost right on how to turn it on everywhere but the
/backhand/ location. You just want "Backhand off" in the /backhand/
location definition.

The FAQ outlines all of the candidacy functions (I think). Let me know
of any errors or omissions.

It covers them all except "removeSelf"
