GETTING STARTED CHP. 5

Double-click the Cut operation in the Undo pane. The Cut and Trim/Crop operations are both undone in

the waveform and moved to the

Redo pane.

To quickly undo/redo operations in the

Undo/Redo History window, double-click the operation.

Clearing the Undo/Redo History for the current file

Clearing the current file’s Undo/Redo History frees up disk space by deleting the file’s temporary undo/redo

files. However, deleting these temporary files prevents you from undoing changes made to the file since it

was last saved. To clear the undo/redo history for the current file, go to the

Special menu, choose Undo/Redo

History

, and choose Clear from the submenu.

Clearing the Undo/Redo History for all open files

Sound Forge also allows you to simultaneously clear the undo/redo history for all open files. Once again,

however, you cannot undo any previous changes once these histories are deleted. To clear the undo/redo

history for all open files, go to the

Special menu, choose Undo/Redo History, and choose Clear All from the

submenu.

Selecting status formats

The status format determines how Sound Forge displays a file’s position and length information. The

following table briefly describes status formats that Sound Forge supports (hh=hours, mm=minutes,

ss=seconds, and ff=frames).
