How do I turn off multiple objects in the Session Window?
Solution
Objects in the Session Window can be individually toggled
for visibility by enabling or disabling the visibility check box, if you have
many objects loaded toggling visibility can take a long time.
To toggle multiple objects together perform the following.
Holding the SHIFT key select the first and last objects you
want to toggle visibility for, then check one of the object’s visibility check
boxes, all the selected objects will be displayed or hidden.
To toggle a non-consecutive series of objects hold the CTRL key and select the objects, then check one of the object's visibility check boxes, all the selected objects will be displayed or hidden.
