The easiest way to remove a portion of your record is to highlight the undesired segment and select Edit > Clear. The section of the data on the selected channel will be deleted and the data following will be shifted forward in time. To delete the highlighted section of data from all channels, select Edit > Clear All.
To manage data without creating a time shift, highlight a segment of data and select Transform > Math Functions > Connect endpoints. The software will susbstitute the highlighted data with a linear interpolation based on the values at the left and right edges of the selected area.
