The general selection window is used for various purposes, e.g. selection of an attribute set or restoring/saving a session.
The window contains following standard buttons:
renames the object.
toggles the object to "Read only." Use this option to protect any object from overwriting.
removes the object.
When the user clicks Survey > Session, there are three options: "Save..", "Restore.." and "Auto..", which enables the user to select a session which will restore, by default, each time the user opens OpendTect.
