alt+arrow keys do not work

[PgLoLo]

In new version of jupyter notebook interfaces alt + left and write arrow keys does not work. In previous UI alt + left key was home and alt + right key was end. Now it is something like ctr + arrow keys? With some changes? IDK, something like that.

Is it an intended change? Is there any way to configure alt + arrow keys back to home and end? Or maybe there is a way to switch back to old UI version of jupyter notebook?

Thanks.

This behavior is super annoying. Any way to workaround this and remap alt + left key to Home and alt + right key to End (as it was in the previous Jupiter notebook UI)?
