@SadmanSobhan That is for notebooks and i already mentioned how to bring the line numbers in the question description. In the documentation for jupyter lab from here http://jupyterlab.readthedocs.io/en/stable/user/interface.html?highlight=Shortcuts, i couldn't find the shortcut keys for line numbers. — Saranraj Nambusubramaniyan, Mar 30 '18 at 11:34

you can turn this on by default by going into Settings --> Advanced Settings Editor:

As you can see from the screenshot, you can edit other features as well and easily set them back to default by deleting your 'User Overrides'

Go to Settings > Advanced configuration and add:

{
    "codeCellConfig": {
        "lineNumbers": true
    }
}

You can go to View -> Show Line Numbers:

which will display line numbers in the notebook:

Late reply, but it'll still help others!

For Windows users, just hit Shift + L

Yeah it works for the Macs too, but I didn't know the keyboard commands for Macs! :) – Neeraj Khadagade May 26 '21 at 07:30

In your Jupyter Lab, click the chain, View -> Line numbers. This solution is from this GitHub issue.

I'm new at this so don't flame me. But Frank said from View -> Show Line Numbers. I did this from main JupyterLab window. I'm using version 3.5.0.

Please, put it as a comment to Franck and cut it to minimum words (it's hard to navigate it back otherwise). Also, please make it clear if it worked for you. – Julia Meshcheryakova Dec 10 '22 at 21:15
