In Jupyter Notebook you can toggle the cell output by going into command mode and pressing "O". This command does not work on Jupyter Lab, and I don't see an option to add it. Is there a way to do this, even if it means writing the code for the command?

@Arkady.A Looks like it to me. – Brian Keith Mar 04 '20 at 19:02

1JupyterLab is different than the classic notebook interface covered at the possible duplicate. – Wayne Mar 04 '20 at 21:43

@Wayne True but the solution of adding ; at the end of an output you want to suppress also works in lab – Brian Keith Mar 04 '20 at 21:49

In Jupyter Notebook you could easily just double click on the cell output to hide it.
This doesn't appear to work in Labs.
Labs has functionality to set keyboard shortcuts.
Settings>Adv Settings> Keyboard Shortcuts You can then add your own shortcut. This example uses "H".
{ "shortcuts": [
//First you can optionally make room for your new hotkey if it is taken.
// {
// "command": "imageviewer:flip-horizontal",
// "keys": [
// "H"
// ],
// "selector": ".jp-ImageViewer",
// "disabled": true
// },
// Then assign a new hotkey
{
"command": "notebook:hide-cell-outputs",
"keys": [
"H"
],
"selector": ".jp-Notebook:focus",
"disabled": false
}
]
}

Thanks ! Works well for me (version 3.1.14). Some notes: to open this file "settings" -> "advanced settings" -> "Keyboard Shortcuts". I noticed that single letter shortcuts key **must** be in uppercase in this config file (if not they are ignored), but their usage is **lowercase** only. Weired – Bruno Duyé Oct 05 '21 at 13:49

As Arkady said, this looks like a duplicate from this post. Note, you can also do this in the sidebar if you don't want to code it.

I'd also add that these abilities are presently available under the `View` menu in JupyterLab. There is `Collapse` and `Expand` sections for selected code, selected output, all code, or all outputs. – Wayne Mar 04 '20 at 21:46

Click on the blue vertical bar to the left of the output or code cell to hide/toggle them. Found this when I accidentally clicked on it :)
