IPython Notebook keyboard shortcut search for text

Is there a keyboard shortcut to search for text in an IPython Notebook?

I looked under Help | Keyboard shortcuts and there are lots of cool shortcuts but none for searching for text?

The notebook is running in FireFox on Ubuntu.

There is a find-and-replace command in Jupyter. It's key binding is F (command mode):

Of course you can find text with the browser's functionality, (I find it sometimes better), but the command in Jupyter is also very useful. I use a lot that function Replace in selected cells when I copy-paste a bunch of code and then change variables or something like that:

(Note: You can launch the Command Palette with shift+ctrl+P, and browse or run other commands)

:Embarassed: "Running in" means use the browser "find text on this page" shortcut. Firefox shortcut for this is ctrl - F.

As of Jupyter Lab v1.0.2 the CTRL+F twice press trick described in my comment above doesn't seem to work anymore.

I found the internal search functionality of jupyter lab pretty annoying, since it only searches in the current cell. I wanted to directly access the native browser search with CTRL+F.

To disable jupyter lab search function (and use browser search instead):

open Settings\Advanced Settings Editor
add the following to User Preferencec:

{
    "shortcuts": [
    {
            "command": "documentsearch:start",
            "keys": [
                "Accel F"
            ],
            "selector": ".jp-mod-searchable",
            "disabled": true
        }
    ]
}

This will override the System Default, with "disabled": true added, and enables Browser CTRL+F in all Jupyter Lab instances.
