I've been developing eLearning lessons in TechSmith Camtasia for years. One of the biggest drawbacks to using the tool was the inability to group Timeline objects. That shortcoming has been addressed in version 8 of the Studio.
Creating a group is simple. On the Timeline, select two or more objects (you can select objects on the same Track, or objects across multiple tracks). Right-click the selected objects and choose Group.
Once the group has been created, moving the group left or right on the Timeline moves all of the objects that are included within the group.
I tend to create multiple groups in my projects. I find naming my groups helps me avoid confusion when I want to work with one group or another. To name a group, right-click the group and choose Rename Group. You can give a group any name you like.
Suffering from "group regret?" You can right-click any group and choose Ungroup. And if you'd like to see the objects that make up a group, click the group's plus sign to expand the group.
