Bookmarks let you save specific selection states. This allows you to review them later, and share them with other users.
Do the following:
Make the selections on the sheet that you want to save as a bookmark.
Click in the toolbar.
Click Create new bookmark.
The name of the sheet and a summary of the selections are used as the title of the bookmark.
If you want another name for the bookmark, change it under Title.
The bookmark is automatically saved.
When creating or editing a bookmark, you will see the possible alternate states that have been bookmarked. If a state includes selections, then the set expression for the selections is also shown.
You can copy the set expression by clicking Copy.
