Deselect is a term we use to describe the act of removing a selection, but there are antonyms that we can use to describe the opposite action. If we want to select something again or add to an existing selection, we can use antonyms such as "choose," "pick," or "select." These words imply that we are making a positive decision, rather than cancelling a previous one. Other antonyms for deselect include "include," "enlist," and "add," all of which suggest that we are expanding or enhancing a selection, rather than retracting or cancelling it. By using these antonyms, we can convey the opposite meaning of deselect and describe actions that involve making a positive selection.
