Sometimes it is useful to use a mixture of cases in a sequence. You might want to flag an interesting region and have it easily identifiable in other views. You can change the case of a selected region of a sequence in MacVector using the Edit | Transformations menu.
The case is maintained in all of the related MacVector sequence display windows. In particular, the plain text output windows from all of the analysis functions honor upper/lower case so you can easily identify results surrounding your region of interest.
