    if verLessThan('matlab', '8.1.0')
        snippet.activeEditor = editorservices.getActive;                % Get the active document in the editor
    else
        snippet.activeEditor = matlab.desktop.editor.getActive;         % Get the active document in the editor
    end
    snippet.activeEditor.JavaEditor.insertTextAtCaret(snippet.txt);     % Insert text at the current position
    if isfield(snippet,'snippet')                                       % Delete SNIPPET (or replace it by its original value)
        snippet = snippet.snippet;
    else
        clear snippet
    end;
end

This is great, thanks! Small bug when filename already has ".m" at the end. "snipper_file_name" should probably be "snippet_file_name" in a couple of places.

Clever idea!
