I'm trying to reorder cells in a jupyter notebook. I've read other posts that suggest that the "edit" menu should have "move cell up" and "move cell down" menu items, but it doesn't.
The cell I want to move is selected.
Jupyter was installed less than a month ago using pip. I'm using Chrome under Windows 10.
Thanks.

I'm using Jupyter Lab.
I would like know if there is a way to select some big part of the ipynb file without scrolling (in order to run the selected cells).
I guess a good way to do it would be by using the table of content on the left, but the "problem" is that when I click on a new part, it activates the first cell of this part so I can't use SHIFT + right click.
I have seen that in some IDEs, when you print something , a new window opens up.
my question is that is it possible to have the same thing for jupyter notebook ?
P.s:
It would be better if it was customizable; like being able to change the background color of the new window.
You'd want the newer generation of Jupyter interface, JupyterLab. (At least if you want this soon. I don't know what will be possible as Jupyter notebook 7 starts using more of the underlying machinery that JupyterLab uses.)
Default JupyterLab
Using default current JupyterLab, you can make a separate window for any output that you can drag around and arrange how you want. Right-click on an output cell and select from the menu 'Create New View for Output'. That will open a new window that respects the current JupyterLab theme. (There's a lot of theme adapting abilities so maybe that can provide what you need as far as background.) Once the new window is generated you can click and drag it around the JupyterLab window to arrange it relative to the notebook and then release when you have it outlined the way you want. You can try it right in your browser by clicking this link and letting the session spin up.
(This ability was covered in an answer to a similar question 'How to display Jupyterlab output in new tab?'.)
Similarly, you can have a window that keeps updating with the most recent output by using an attached console and toggling on 'Show All Kernel Activity'. When you have a notebook open, either right-click and select 'New Console for Notebook' or go under the main 'File' menu and select 'New Console for Notebook'. This will open a console and you can then right-click on the console pane and toggle on 'Show All Kernel Activity'. As you run things in the notebook, the output will show at the bottom of this window as well. Even rich output like plots and dataframe displays. You can click on the tab and drag to arrange this window as you wish in the main JupyterLAb pane. See some example images using this here and here.

It's not a separate window; however, a nice feature of JupyterLab is switching to 'View' to 'Render Side-by-Side' where the output goes to the side of the code cell and not below. Alternatively, you can modify the output cell in some ways like you could do in the classic notebook interface, see here.
Sidecar extension of JupyterLab
There's an extension called sidecar for Jupyterlab that I believe has more options. I wonder if you could combine widgets to control the background as you seek. Don't know about the layering possibilities there.
ipylab extension of JupyterLab
ipylab has even more abilities than sidecar for customization, with 'SplitPanel' and 'DockPanel'. Scroll through the examples shown to get an idea of the possibilities. There's also a 'launch binder' badge so you can try it out.
(You may also want to see Related projects listed at the bottom of ipylab's github page.)
I.e. for one cell in the notebook, the editing version and rendered version are presented side-by-side so you don't lose your place between editing and checking the rendered version. Particularly for Markdown cells.
Are there any plugins or add-ons which achieve this? Perhaps there is a hacky way to have two browser windows where one updates rendered cells in real time and the other is used for editing. I guess even something as simple as the "render cell" command being piped to a different window would do the trick.
I assumed that there would be a keyboard shortcut to begin typing within a newly created Jupyter Notebook cell, but I titled my question asking if it even exists to not build any assumptions. If it does exist, please also include in your answer the shortcut to use.
I will try to provide as much relevant information as possible that will help in answering my question:
I installed Jupyter Notebook on my Windows 10 PC from their website (not using Anaconda). I view and edit Jupyter Notebook files in my Google Chrome browser. After running a cell with Ctrl+Enter, I press b to create a new cell below. I would like to immediately begin typing within that cell without having to click inside that cell with a mouse.
Thank you
There is a builtin-shortcut that does exactly what you want. Just enter a cell an press Alt + Enter. This will execute the current selected cell, insert a new cell below it and enter edit mode.
Notice, that this also works if you are not in edit mode.
My setup is a little bit different than yours. Here is a reference.
I know one can hide the code in the entire notebook - just looked at this question and magnificent answer How to hide code from cells in ipython notebook visualized with nbviewer? - but can one do that for individual notebook cells?
