There are also some scripts here for manipulating wireframe states:

Stuff like hide all edges just of the selected object, etc...

There is also an experimental function for the Scene Browser that you can enable in moi.ini:

[Scene Browser]
EnableSelectionSubTypes=y

That adds 2 additional entries to the Types section of the Scene Browser: "Selected", and "Unselected" , if you expand those then the controls under them will be targeting a combination of selection and type. For example doing a hide on Unselected > Edges will hide all edges that are unselected and leave selected edges alone. These controls may still need a little tuning.


Another related area for selection by type is in the "Details..." object properties dialog. There's a report at the top of the dialog on the styles and types for the current selection. The labels for the report are clickable, and will filter selection to that item.

So when you see this for example:


You can click the "4 lines" label in the report there and that will narrow the selection to just those objects. You can also click on the style report labels. You can also hold down Shift to click on multiple labels, like hold down shift and click on both "4 lines" and "Orange" to get both of those, it will trigger when you release shift. Also Ctrl+click will remove those objects from selection instead of filtering selection down to them.
