I have an old pymol session file .
I have a mesh object displayed whose level I can manipulate in predetermined ways using the Action-Level-menu. I however want to pick a level different from the menu options provided .

A further complication is that I have deleted the original map object and want to avoid going looking for it.

Is there a way to pick a level for a mesh object that is not pre-programmed into the Action menu .

Thanks
Hari
