$\blacktriangleright$ To remove a definition from a document

$\blacktriangleright$ To remove all definitions in a document

If you have worked the preceding examples, you have made several definitions and you should remove them before continuing. Definitions that you do not remove remain active as long as a document is open. As a default, definitions are saved and then restored when you reopen a document. You can change this setting so that exiting a document in Scientific Notebook will remove your definitions. See Saving DefinitionsDM5-3.tex#Saving definitions for more discussion of Save Definitions, Restore Definitions, and Clear Definitions.
