Snap-To ... > Snap On - Enable Snap-To mode. When Snap-To mode is enabled, the selection will be
constrained to the nearest interval on the time scale, by default the nearest second. So if you click and
drag from 4.2 seconds to 9.8 seconds, it will result in a selection from 4 seconds to 10 seconds, exactly.
You can change the units that are snapped to using the "Set Selection Format" option in the View
Menu .

Set Selection Format - lets you choose the formatting that is displayed at the bottom of the window
indicating the current selection time. Options include film, video, and audio CD frames, seconds +
samples, or pure time. If you turn on Snap-To mode in the Edit Menu, the selection will snap to the
frames or other quantization you have selected in this menu.
History... - Brings up the history window. It shows all the actions you have performed during the
current session, including importing. The right-hand column shows the amount of hard disk space your
operations used. You can jump back and forth between editing steps quite easily by simply clicking on
the entries in the window, the same as selecting Undo or Redo many times in a row. You can also
discard Undo history to save disk space. The history window can be kept open while you work.
