Keyboard shortcuts TAB shift+Tab not working in Chrome/firefox/Edge

I recently started used anaconda & jupyter notebook. Tab, Shift Tab etc shortcuts don't work on any of the browsers.

I tried spyder and all worked fine.

But i would love to use jupyter and any help you can provide to make these shortcuts work wud be appreciated.

Thanks!

Reproduce the missing Tab and Shift+Tab shortcuts in Jupyter Notebook using Chrome, Firefox, and Edge, comparing the behavior reported against Spyder. The issue names no files or tests, so first locate the notebook keyboard-shortcut handling and establish a reproducible failing case; done means both shortcuts work in the affected browsers.
