Hi,

 instead of defining an environment variable:

<assign|uni|<big|cup>> 

what you need to do is define a macro:

<assign|uni|<\macro>
  <big|cup>
</macro>> 

Notice the way the macro is written: it expands to a document tag (hidden in
the default view mode for source code (try setting the preferences in
Document->Source->Preferences… to show “raw”). This is necessary.

Now use the macro typing \uni.

Of course you can define keyboard shortcuts:

(kbd-map
 (:mode in-math?)
 ("C-u" (make 'uni)))

Also, no need to go to source mode at all! Don’t inflict unnecessary pain on
yourself: To insert below / above, select the symbol then hit C-b or C-a.  ;)

Cheers,
