Jupyter keyboard shortcut for running a specific cell

Question

In my workflow with Jupyter notebook, I have a cell like:

%run myscript.py

Which loads the latest version of a script with functions I'm using. I am constantly updating this script and using its function in my notebook. Therefore, I find myself constantly going back to the first cell and running it. It would be very convenient if there was a keyboard shortcut to do that (e.g. run the first cell). Does it exist?

Answer 1

You can click "Ctrl + Enter" to run only the chosen cell no matter it is "edit mode" or "command mode".

If you want to know more available commands, just input Esc to change you current mode to "command mode" and input "h" to show the Keyboard shortcuts modal.

Answer 2

An important update If you install nbextensions then there is a nice widget for that called

"Initialization cells"

Here is the link to nbextensions https://jupyter-contrib-nbextensions.readthedocs.io/en/latest/install.html

The following comments are my old comments and can be neglected.

You can do it by running the following code:

%%javascript
Jupyter.notebook.execute_cells([0])

Note: the cell number in this command is different from the cell number that appears on the left side of the cell in Jupyter. For this command, the cell number is based on the order of the cell in the Jupyter Notebook, from top to bottom.
