For what exactly you want to add an inst var? For the multiple selected items? For 
the current (single) selected item?
The multiple selected items are stored in an inst var in the model, ie. in class 
OBMultipleSelectionColumn. The current (single) selected item is already stored in 
OBColumn.
The problem with the arrows keys is that they are not properly handled by 
PluggableListMorphOfMany. In fact, this class only inherits the behavior of 
PluggableListMorph regarding arrow keys. This means that the first element (before 
using the arrow key) is still (multiple) selected while the new element after using 
the arrow key is selected normally as if only single selection would be possible.
I can adapt this in the context of OmniBrowser to de-select the first (multiple) 
selected element after pressing a special key like arrow.

You mean that you only get the package view if Monticello is loaded? Well, this 
should be possible to do.
