I want to save only the first 2000 packets of a capture, thereby my save
file will be small.

I thought I should create a display filter and save only the displayed
packets. The problem is, I cannot find the filter field corresponding to
a packet number. Then I thought I could filter on the time field but
when I select protocol time in the display filter, add expression
dialog, then select <, the error message tells me the field cannot be
tested with "<". 

Which leaves me with what I'm sure is simple, dumb question:

How do I save only the first 2000 lines of a captured set of packets?

I have read about 4 hours today but have not found the answer.
