Hi! I think the texi documentation of the key triggering 'org-babel-load-in-session' is not up to date. The documentation says 'C-up' but it looks like it should be 'M-up'.
Suggestion for a patch: Modified doc/org.texi diff --git a/doc/org.texi b/doc/org.texi index b21c93d..05c1575 100644 --- a/doc/org.texi +++ b/doc/org.texi @@ -15792,6 +15792,6 @@ are active: @kindex C-c C-o @item @kbd{C-c C-o} @tab @code{org-babel-open-src-block-result} -@kindex C-up -@item @kbd{C-@key{up}} @tab @code{org-babel-load-in-session} +@kindex M-up +@item @kbd{M-@key{up}} @tab @code{org-babel-load-in-session} @kindex M-down @item @kbd{M-@key{down}} @tab @code{org-babel-pop-to-session} My 1 ₰, Marco -- http://www.wahlzone.de
