Now open any notebook click help>keyboard shortcuts. Option 2 - custom shortcut (without GUI):įor this, you need to edit the custom.js file which is typically located at ~/.jupyter/custom/custom.js (if it doesn't exist, create it). The the intro page will have a new tab called nbextensions click it and enable Keyboard Shortcut Editor. List all magic commands available on your Notebook.For versions less than 5: Option 1 - quick hack:Ĭhange the cell type to raw then back to code: Esc R Y will discard the output. Here are what I think are the most useful magic commands together with some examples of their use. To run a magic command just enter them at the start of your Notebook cell followed by any other normal cell input. Many magics can be run as either a line or cell magic. They receive the whole block as a single string. They can in fact make arbitrary modifications to the input they receive, which need not even be a valid Python code at all. Unlike line magic functions, they can operate on multiple lines below their call. Line magics can be used as expression and their return value can be assigned to variable.Ĭell Magics start with double percent (%%) characters. ![]() The rest of the line is the Magic argument passed without parentheses or quotes. Line Magics start with the percent (%) character. There are two types of magic commands, Line Magics and Cell Magics. Magic commands are shortcuts that can extend the capabilities of Jupyter Notebooks. Keystrokes EffectĮSC a create a new cell above current cellĮSC b create a new cell below current cellĮSC Shift Up/Down Arrow select adjacent cells in the up or down directionĪs I said before I think these shortcuts are the most useful but there are a bunch more that you see by clicking Help->Keyboard Shortcuts on your notebook. It's a useful habit to get in to doing and doesn't affect the operation of the shortcuts in any way except to ensure that you're in the correct mode before they're run. I have pre-pended each of the below commands with the Escape key just as a reminder that you need to be in Command mode before running them. This will open a dialog box with a list of all available keyboard shortcuts. Shift M merge selected cells into one cell To view a list of keyboard shortcuts in a Jupyter notebook, you can go to the Help menu and select Keyboard Shortcuts. Shift Enter run the contents of cell and move to the cell belowĬTRL c/x/v copy/cut/paste text operations in the cellĪLT Left/Right Arrow goto beginning/end of the current line in the cellĬTRL Home/End goto first/last character of the cellĬTRL dedent selected or current line in a cellĬTRL / comment/uncomment selected lines in a cell Here are what I consider to be the most useful keyboard shortcuts.ĬTRL Enter run the contents of cell and stay in the cell To switch from edit mode to command mode you should press the Escape (ESC) key first. ![]() In edit mode the current cell has a blue border around it. You know when you're in command mode since the current cell will have a green border around it. When entering keyboard shortcuts, you should remember that Jupyter has two modes of operation, command mode and edit mode. We will be talking about keyboard and magic shortcuts. ![]() The answer is yes there is and they are not that hard to find using the Help system but I thought it might be useful to bring the most common and useful of them together in one short article. I think it’s fair to say that Jupyter notebooks are fast becoming the de-facto tool of choice for many data engineers, data scientists and even software developers for quickly setting up proof-of-concept data wrangling jobs or even as a full-blown development and data analysis environments. Almost uniquely, a Jupyter Notebook lets you code, analyse, document and visualise your data and data processing all in one place, right there in a browser window.Īs you use Notebooks for any length of time, you’ll find yourself typing in the same commands over and over again and you might start thinking if there are any tips and tricks available on how to be even more productive using them. ![]()
