<I

selected sample both belong to the selection and will be used for the
following actions. So even if you not selected a <I
CLASS="EMPHASIS"
>range</I
>
but only a single sample, the selection will never be really "empty". So for
example if you see no selected range, the "delete" function applies to that
single sample.
</P
><P
> The easiest way of selecting a range of samples is just to do that
with mouse. It works like you are used from other applications: just press
the left mouse button at the point you want to let the selection start
and release the button where you want it to end.
</P
><P
> If you want to move or adjust the selection's start or end, you can move the
mouse cursor near to the start or the end of the selection until it changes
from the standard arrow cursor into the left-right arrow cursor and then
press the left mouse button and adjust.
