No need to export the parameter. No external process will need it, and
zshenv is read for every zsh-instance, that also reads zshrc.

Generally, I wouldn't advice people to set the parameter. Setting the
terminal into "keyboard-transmit-mode" (which is what the smkx terminfo
entry does) while the line editor is active is the right thing to do,
IMNSHO. Otherwise, you can't rely on values from $terminfo to be
correct. The parameter is really meant for people who know what they are

I'm just mentioning this for the innocent lurker, who might be wondering
what we're on about. I don't know of your background and you might
indeed know what you're doing. This is not meant to be offensive.
