When a material is moved, a copy is created and it is added to the new category. If the material is copied into the root node, its original category is maintained and recreated in the new library. There are two ways to move materials:

• Drag and drop. You can drag swatches or materials from a library to the Materials in This Document section in the Materials Browser. You can also drag materials from a library to another library. A new copy of the material is created and saved with the drawing.
• Shortcut menu. You can use the shortcut menu to copy a material to a new library. Use the Add To option and then select, for example, material in the library copied to the document or a library material copied to another library.

Any in-document and unlocked material can be renamed in-place using the materials shortcut menu.

You can search the materials in all open libraries based on the material’s name, description, and keyword information entered in the Materials Editor. All the materials are filtered to show only those matching the search string. Only the materials that have a match for the search string are displayed. Click the X button in the search box to clear the search and return to viewing the unfiltered library.

The search results depend on the library you have selected in the tree view. For example, if you select the Library root node, it displays the search results for all matching materials in the selected library. But if you select a category, it searches only within that category.

You can delete a selected and unlocked material by using the shortcut menu or with the Delete key. Locked materials cannot be deleted from the Materials Browser or from the shortcut menu.
