- test_clear_search_pat()                               
*test_clear_search_pat()*
-               Clears the last used search pattern (|/|) and the substitute
-               pattern (|:s|). This is useful for testing conditions where
-               these patterns are not set previously.
- 
  test_feedinput({string})                              *test_feedinput()*
                Characters in {string} are queued for processing as if they
                were typed by the user. This uses a low level input buffer.

hundred-and-one symptoms of being an internet addict:
65. The last time you looked at the clock it was 11:30pm, and in what
    seems like only a few seconds later, your sister runs past you to
    catch her 7am school bus.
