While, for the most part, the behavior of the commands Move → Indent left and Move → Indent right is intuitive, there are some instances, especially with multiple projects selected, where the effect of using Indent-Left or Right may not be clear.
For reference, we give a precise description of what happens during these operations. Note that for both these commands, the selected projects must be contiguous and at the same level of indentation.
Indent left: The selected projects are moved to the same level of indentation as their parent. They appear in sequence just after their parent at that level.
Indent right: The selected projects are made the last subprojects of the project that appears just above them at the same level.
