The Shift key sometimes does not seem to work in emacs, when emacs is launched in Jupyter Notebook's terminal (in non-window mode). Other meta keys such as Ctrl and Alt on a PC keyboard work as usual.
When trying to move to the end of the buffer with Shift+Alt+→, nothing happens. This is tested with Jupyter Hub on Ubuntu 18.04, and the clients are Firefox and Chrome.
However, the Shift key seems to work for selecting multiple lines.
I am not sure whether this relates to how browsers handle the Shift key, or where it went wrong.
Does any one have experience using emacs in Jupyter's terminal and know of a fix?
