[Elecraft] RTTY Diddle suppression

[Dan Sherwood]

Anyone,

In the K3 utility, how do you insert the control character "IM" using the
computer keyboard when editing a RTTY memory?

I'm trying to cut short the long idle tail so the DX stations don't double
with me when answering my responses.  I tried entering IM and cntl-T.
Neither works.  Only sending "IM" on the paddles in real time seems to work.

Thanks,

Dan
