[Elecraft] How to measure keyed waveform

[Larry - WA2DGD]

Hello all,

What is the proper way to look at one's keyed waveform on a scope?
 I was thinking of using a BNC T connector, with one end on the Ant.
terminal of the K2, dummy load to the other end and the tap would go the the
scope. Should I connect it directly to the scope with a short length of coax
or use the scope probe. (which is compensated for a nice square wave.)?
What is the correct way to trigger the scope. Should it be tied to the
Keying line or let the scope autotrigger on the rigs output? If you should
use the key line, what is the easiest way to do it if the rig has a built in
keyer?

Thanks in advance,

Happy Holiday
