The most basic method of selecting Objects is to left-click them in the Viewport. Clicking an Object will deselect any currently selected Objects and select the new one instead. If you hold down the Ctrl key while you click a new (unselected) Object, the new Object is added to the selection. If you hold down the Ctrl key while clicking a selected Object, the Object is removed from the selection.

This method is good for selecting small numbers of Objects or several isolated Objects spread out across a Level, but it can be slow and tedious for selecting large numbers of Objects.

Selecting Objects in the World Outliner

The World Outliner is a panel in the Editor that contains a hierarchical tree view of all Objects in the level. It is located at the left-hand side of the Editor window.

You can select and deselect individual Objects in the list the same way you would in the Viewport.

Hold down the Ctrl key and click multiple Objects to select all of them. The Objects don't have to be in sequence.

Grouping Objects

To group two or more Objects together, select the Objects, then do either of the following:

Right-click one of the selected Objects to bring up the context menu, then select Group.
Use the Ctrl + G keyboard shortcut.

Ungrouping

The Ungroup option removes all Objects from the selected groups and deletes the groups.

For groups that are unlocked, the ungroup operation will remove the selected Objects from the group without attempting to keep them within any existing group hierarchy.
