Hmm, that's right. Commonly don't remember any key, just using it as a 
kind of natural language.

After M-x shell RET input of env RET should display environment vars.

Like

SHELL=/bin/bash

Or, questioning for an alias:

$ type en
$ en ist ein Alias von »~/MY_PATH/emacs --debug-init --font 'Liberation 
Mono-18' &«.

There is one caveat: AFAIU vars are loaded only once at startup. If some 
of this vars changes  during session, Emacs doesn't notice that, needs a 
restart.

Nothing uncommon here so far. Works as expected.

Cheers,
