No, but _REF_EXTRA gives you the names.

Is this what you want to do?

IDL> test, out1=out1, out2=out2
Keyword name: OUT1
Input value:
<No name> UNDEFINED = <Undefined>
Keyword name: OUT2
Input value:
<No name> UNDEFINED = <Undefined>
IDL> help, out1, out2
OUT1 LONG = 0
OUT2 LONG = 1

Here's my routine:

pro test, _ref_extra=e
compile_opt strictarr

for i = 0L, n_elements(e) - 1L do begin
print, e[i], format='(%"Keyword name: %s")'
print, 'Input value:'
help, scope_varfetch(e[i], /ref_extra)
(scope_varfetch(e[i], /ref_extra)) = i
endfor
end
