speedbar: Mouse Bindings

 
 2.3 Mouse Bindings
 ==================
 
 The mouse has become a common information navigation tool.  Speedbar
 will use the mouse to navigate file systems, buffer lists, and other
 data.  The different textual cues provide buttons which can be clicked
 on (SeeBasic Visuals).  Anything that highlights can be clicked on
 with the mouse, or affected by the menu.
 
    The mouse bindings are:
 
 ‘mouse-1’
      Move cursor to that location.
 ‘mouse-2’
 ‘Double-mouse-1’
      Activate the current button.  ‘Double-mouse-1’ is called a “double
      click” on other platforms, and is useful for windows users with two
      button mice.
 ‘S-mouse-2’
 ‘S-Double-mouse-1’
      This has the same effect as ‘mouse-2’, except it is called a power
      click.  This means that if a group with an expansion button ‘+’ is
      clicked, any caches are flushed, and subitems re-read.  If it is a
      name, it will be opened in a new frame.
 ‘mouse-3’
      Activate the speedbar menu.  The item selected affects the line
      clicked, not the line where the cursor was.
 ‘mouse-1 (mode line)’
      Activate the menu.  This affects the item the cursor is on before
      the click, since the mouse was not clicked on anything.
 ‘C-mouse-1’
      Buffers sub-menu.  The buffer in the attached frame is switched.
 
    When the mouse moves over buttons in speedbar, details of that item
 should be displayed in the minibuffer of the attached frame.  Sometimes
 this can contain extra information such as file permissions, or tag
 location.
