Overwrite timeline events with the Trimmer selection
The standard behavior of the  Trimmer is to perform punch-in edits on the timeline: when you add media to 
the timeline, the events created by the Trimmer are laid over existing  events on the timeline. You can delete 
or move the events you create with  the Trimmer without changing the underlying events.
If you want to replace the contents  of the timeline when creating events from the Trimmer, select the 
Enable Timeline Overwrite  button  . When Enable  Timeline Overwrite is selected, ripple  editing is not 
available.
Using the Trimmer History list
The drop-down box at  the top of the Trimmer lists files and events that have been opened in  the Trimmer.
To open a recently  used file, choose its file name from the Trimmer History drop-down list.
To sort the list, click   the Sort Trimmer History  button  . The files in the drop-down list are sorted  in 
alphabetical order. To sort in reverse alphabetical order, hold the  Ctrl key while clicking on the Sort  Trimmer 
History button.
To clear the list,   click the Clear Trimmer   History button  .  All files in the history drop-down list are 
removed.
To remove a single  file from the list, click the Remove Current  Media from Trimmer History button  . The 
media file is removed from the Trimmer  History drop-down list and the Trimmer window is blank.
