Searching and filtering in the LMS is now much more powerful. Administrators can perform multiple searches, make selections and perform actions on those selections. The LMS retains selections throughout multiple searches.
How to take advantage of this feature
One common way to use this feature is for enrolling multiple users in a course. You can search for a user, tick their box and then search for another user. You can do this multiple times without being concerned that your selection will be forgotten.
