HyperSource provides two ways of sorting stacks: sorting by author/keyword and sorting by selecting.* You can also enter search strings in the message
box to find instances of an author name or keyword*. Sorting by author/keyword is useful especially when you want to do an 'or' search (see below).
Click the "sort" button to sort by author or keyword. Choosing "author" will sort the stack alphabetically by author. (If you want to find works by a particular author use the keyword sort). If you choose to sort by Keywords you will be prompted to enter the relevant strings (separated by commas) in the dialog box. If you enter more than one keyword, you will be asked if you want to match any ('or' search) or all ('and' search).
