Jupyter/IPython Notebooks: Shortcut for “run all”?

Question

Is there a shortcut to run all cells in an IPython notebook?

And if not, does this have a specific reason?

Answer 1

For the latest jupyter notebook, (version 5) you can go to the 'help' tab in the top of the notebook and then select the option 'edit keyboard shortcuts' and add in your own customized shortcut for the 'run all' function.

Answer 2

There is a menu shortcut to run all cells under Cell > "Run All". This isn't bound to a keyboard shortcut by default- you'll have to define your own custom binding from within the notebook, as described here.

For example, to add a keyboard binding that lets you run all the cells in a notebook, you can insert this in a cell:

%%javascript

Jupyter.keyboard_manager.command_shortcuts.add_shortcut('r', {
    help : 'run all cells',
    help_index : 'zz',
    handler : function (event) {
        IPython.notebook.execute_all_cells();
        return false;
    }}
);

If you run this code from within iPython notebook, you should find that you now have a keyboard binding to run all cells (in this case, press ctrl-M followed by r)

Answer 3

Easiest solution:

Esc, Ctrl-A, Shift-Enter.

Answer 4

I've been trying to do this in Jupyter Lab so thought it might be useful to post the answer here. You can find the shortcuts in settings and also add your own, where a full list of the possible shortcuts can be found here.

For example, I added my own shortcut to run all cells. In Jupyter Lab, under Settings > Advanced Settings, select Keyboard Shortcuts, then add the following code to 'User Overrides':

{
    "notebook:run-all-cells": {
      "command": "notebook:run-all-cells",
      "keys": [
        "Shift Backspace"
      ],
      "selector": ".jp-Notebook.jp-mod-editMode"
    }
}

Here, Shift + Backspace will run all cells in the notebook.

Answer 5

As of 5.5 you can run Kernel > Restart and Run All
