In Tablature mode, I input frets onto the six strings                           
and the neck is divided by time.                                                
frets --> strings,time                                                          
                                                                                
In Box mode, which is more familiar, actually, I input time onto the            
six strings and the neck is divided by frets.                                   
time --> strings,frets                                                          
                                                                                
In Tablature mode, I set a clip interval using                                  
"[" (left bracket) for the interval start time and                              
"]" (right bracket) for the interval end time                                   
                                                                                
The time in box mode is always referenced to the start of the clip interval.
