You can select multiple keyframes or
            channels to edit them in tandem. Do this, for example, to modify
            every second keyframe in an animation curve or to apply the same
            modification to two or more channels from different folders.
         
         NoteYou can select a
               channel in Move or Select mode by clicking its name in the channel
               hierarchy, or clicking the channel with the cursor.
            
         To select multiple channels:
         
         
            - From the Edit Mode box, select Move or
               Select.
            
- Click a channel in the hierarchy to select
               it. 
               TipYou can also select
                     channels by clicking their animation curve or track.
                   
When a channel is selected,
                  its name and animation curve are highlighted. As well, if the channel
                  corresponds to an element in the image window, the element is highlighted
                  there. For example, if you select the Axis channel for a clip, its
                  axis is highlighted in the image window.
                
- Shift-click
               another channel to add it to the selection. Shift-click a selected channel to
               deselect it.

            - From the Edit Mode box, select Move or
               Select.

                  dragging the selection box over the first ten frames of an animation
                  selects all keyframes that fall within those ten frames.
