Copy and paste

[Bacbia3696]

Thank you so much for such great work,
But I can't paste the text to code block, i tried Control-V but it have no effect, the work around is middle button with mouse ( really not satisfied because lots of the time I didn't use mouse).
I can only paste from text inside note book ( Control-W, Control-Y).
Additionally, I can't use Control-W to delete a word just like I can do in terminal. I didn't find any options to customize keybinding for this extension.
