On toolbar "Insert" icon that inserts footnote has help text "Insert
and should have had "Insert Footnote Directly".
Seems that someone has forgotten that via Insert > Footnote/Endnote
dialog BOTH footnote and endnote can be inserted. You will find supporting
evidence for that in AOO Help.
I have visited Polish, German, French and Russian versions.
Polish, French and Russian versions are INCORRECT,
but in German version you will see CORRECT wording: "Fußnote direkt
einfügen" (*Lang leben diese Deutschen!!! Dreimal hoch...)*
I have neither time nor intention to check other language versions. Hope
follow in my footsteps.
Keep in mind that due change/additon has to be made in AOO Help too -
second icon and its description.
