clicking the ‘edit select’ icon found on the Palette Bar. This selection mode allows you to highlight the desired area for editing or math operations.

When you first enter ‘edit select’ mode and move your mouse in the waveform edit window, the Status Bar reflects the X and Y positions of your cursor as it moves across the window. When a portion of the

waveform is highlighted by clicking and dragging the cursor, the Status R Bar reflects the start and end points of the highlighted area and the total number of points selected. The highlighted area can be adjusted using the up/down and left/right arrows in the following manner:

∙Right arrow - selects the right side of the highlighted area

∙Left arrow - selects the left side of the highlighted area

∙Up arrow - increases the highlighted area

∙Down arrow - decreases the highlighted area

In	normal viewing mode, the up/ down	arrow keys may not seem
to	increase or decrease the highlighted	area in the waveform

edit window, yet the Status Bar indicates the change in selection. Zooming in will display the results in a more efficient manner.

To invalidate a highlighted selection, click past the end of the waveform or click the ‘edit select’ icon again.
