Tool Bar, Tool-Bar or Toolbar?
The "tool bar" versus "tool-bar" versus "toolbar" debate rages on
The English language has a penchant for slowly combining words together over time. Thus "tool bar" has a natural progression to "tool-bar" and then "toolbar".
The "tool-bar" variant is rarely used, almost everyone now uses the term toolbar. But when searching for specific toolbars (or tool bars or tool-bars) don't forget to try the tool bar and tool-bar forms.
See the list of common variants for other spellings and related terms. Advertisers often target these variants in their campaigns, so you may discover new or different tool-bars with some clever searching.
The Toolbar Guide mostly uses the combined form, but the other two forms are also used in order to ensure that the Guide's pages show up in the search results for "tool bar" and "tool-bar" as well as "toolbar". This is a simple form of search engine optimization for compound word keywords.
