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.
