1. Since OBJMGR_VIS toggles the object manager and you always want to see it regardless of its current state, you have to first check whether the object manager is already opened. You can use session.idExists for this. Something like this as an onLoad script should work:
if (session.idExists("wnd[0]/shellcont/shell/shellcont[0]/shell/shellcont[1]/shell[1]")) {}
else
{ session.findById("wnd[0]/tbar[0]/okcd").text = "OBJMGR_VIS";
session.findById("wnd[0]").sendVKey(0); }
2. I don't understand what you mean... what hit list and how do you get there? In general, you just have to use the commands already available in the transaction to get what you need.
