-Basically, the extension allows to copy the original cell into a new one for editing and translating. Optionally, the cell source text can be passed through `google translate` and the result inserted in the new cell. Basic markdown structures (e.g. bold, emphasis, lists) are preserved/restored after conversion, to the best extent, but this is not perfect, and usually one has to correct the text and structures afterward. Similarly, equations are extracted before conversion and restored in the result. It seems that when translating from lang1 to lang2, the best results are obtained by taking English as an intermediate language.

-A metadata indicating the language used is added to each cell. This allows to selectively display cells for a particular language and hide the other ones. As far as they are concerned, code cells are preserved. This way, one can get a kind of multilanguage notebook. A menu is provided to select the languages to display in the notebook.

 ## Configuration
-- Parameters values can be changed using the `nbextensions-configurator`: it is possible to choose the initial source and target languages, to choose to use of google translate engine or not, to specify the initially displayed languages, the position of the language selection menu, and define a keyboard shortcut
-- A *configuration toolbar* is provided which enables to change the main options per notebook. In the configuration toolbar, one can toogle the use of the google translate engine, select the source and target languges, and finally select the language to display.
