anchor.diff:  The 2-step approach just described means that, for example, 'acacia mill.' is enough to recognise Acacia Mill., even though it also matches a section and a subgenus that start out with the same string.  This would **not** be the case if it applied a trailing wildcard right from the start.

   Removing data from a typeahead field works just like any other field - simply remove the text and save.

  +##### You have to select from the list sometimes
   
   Sometimes you cannot identify a single record with text alone, and in those cases you do need to select a suggestion with keyboard or mouse.  Having to select from the suggestion list should be rare, but it is important to know about.  Selecting from the suggestions puts the record's ID in a place the Editor can use, so it resolves any ambiguity in text recognition.

   You can include wildcards (percent, asterisk) as you type and this will be used in the suggestion search.
   
  
positive.code: 
  The Editor provides "typeahead" fields for this type of data.  These are important and powerful controls for quickly identifying a single existing record out of many thousands without having to give its ID.
  
  ### Understanding and using typeahead fields
  
  ####Starting
  
  Typeaheads look like normal text fields, but as you start typing in one, you will see a list of possible choices, or suggestions, appear below the field.
  
  
negative.code:     - Records that start with 'walsh', followed by anything, followed by 'walsh', followed by anything, will be found.
  
  
  ##### Extra information in the suggestion list  
  
  Typeahead field suggestions often show extra information about the suggested records - types and counts for example.  That extra information is shown on the right-hand side of a vertical bar or pipe symbol ("&#124;") in the list.  Don't try to type that extra information because it will mislead the Editor as it searches for suggestions.
  
  ##### Identifying an ID
  
  Typeahead fields ultimately store the ID of the component.  You might be typing a reference citation, but you are actually giving the Editor enough information to find a single unique ID in the database.  Sometimes that might help you understand why the typeaheads work in a particular way.
