Try several times and you'll learn it.

<p class="MsoNormal">In EEGALB tutorial, under the section “Selecting Data Epochs
and Comparing”. As I understood, we need to separate the main dataset
that is has event one, and event 2 into 2 separated datasets that are located in 2 files. Then perform Edit > Select
epochs or events. After that, in the dialog box, need to enter "1" in the
textbox next to position (<b>which will
select all epochs in which the target appeared in position 1-in the attached
file 1</b>), which will select all epochs in which the target appeared in
position 1. This is for the first dataset, then load the next dataset and apply
same process with.</p>
