I can't get CTRL+K and CTRL+J to move between cells in the notebook, when I'm in command mode.
I'm running on a Mac OS X (Chrome browser).
However, SHIFT+K and SHIFT+J works. I'm assuming it's an error with the documentation?
Several keyboard shortcuts are common between Jupyter and Datalab. You may find it helpful to view the Jupyter keyboard shortcut help dialog that is accessible within a datalab notebook. To open the Jupyter keyboard shortcut help dialog, open a datalab notebook, then press Esc to enter command mode, then press H.
