Jupyter Notebook Keyboard Shortcuts: The article contains all the keyboard shortcuts and text snippets that any programmer would share with others during their long sessions of Pair Programming and have been well-received by a majority of the user. These mentioned can save a person countless hours programming and hope that such shortcut is capable of making someone start utilising some of these techniques to grow a more efficient programmer of Python. If a person spends two weeks practising Jupyter Notebook for analysis of data with Python, then will definitely use the shortcuts to compile a shortlist of all favourite keyboard shortcuts/the ones that most programmers use the most maximum.
For certain shortcuts, one must keep in mind that they can enter Command Mode (to perform actions of notebook-level) by simply pressing Esc, and they can return to Edit Mode (a.k.a. back to writing in cells) by pressing Enter. If a shortcut necessitates Command Mode, then one must specify Esc as the first key.
Wondering How to explore & learn Shortcut Keys for various Operating Systems, Computer Software Programs, Social media applications Keyboards? Here is the one-stop destination for all Keyboard Shortcuts, just take a look & memorize regularly for better performance in competitive exams & real-time situations.

What is Jupyter Notebook?
Shortcuts jupyter notebook: Jupyter Notebook is extensively employed for data analysis. If a person started to learn Data Science 2–3 months ago and if they used this tool to explore some datasets (basically a collection of data). They will find that the notebooks documents are documents produced by the Jupyter Notebook App, which can accommodate both code (e.g. Python) and rich text elements like equations, links, paragraphs, etc. The Jupyter Notebook App is an application made for client-server that permits are running and editing notebook documents by a browser.
As a developer, one may prefer to use snippets and shortcuts as much as others do. The Jupyter Notebook App just makes writing code a lot simpler and faster. A programmer must follow one rule: If one started performing some action with the mouse, stop and recall if there is a shortcut present for the task. If there is one – apply it. When one starts using Jupyter Notebook, most of them were unaware of the fact that there are shortcuts for such a tool. Several times, one has to change their cell type from code to markdown, and most of them initially didn’t know-how.
As someone can guess, this caused a person a lot of headaches. To solve this issue, there is a Help > Keyboard Shortcuts link in the menu bar, and one finds that there are a ton of shortcuts present in that Jupyter Notebook. In addition to the shortcuts for the default keyboard, one can also define some of their own. This is accomplished by entering menu options “Help” > “Edit Keyboard Shortcuts” in the Notebook. One must scroll in the dialogue box until they find the action they want and then categorise the key combination in the “add shortcut” option present in the input box.
Note: A person needs to classify the keys by a hyphen (-). One should not forget to click the plus sign button to preserve the new shortcut!
Keyboard Shortcuts
Jupyter notebook hotkeys: In this article, the favourite shortcuts available in The Jupyter Notebook are table down.
First, we necessitate learning about the two modes in the Jupyter Notebook App: command mode and edit mode. And should also memorise all the shortcuts shared within the two modes.
Command mode vs Edit mode
Jupyter notebook keyboard shortcuts: Jupyter Notebooks have two distinct keyboard input modes, and it is something that to be aware of:
- Command mode- binds the notebook-level actions to the keyboard. Symbolised with a blue left margin and by a grey cell border.
- Edit mode- when a person is typing in a cell. Symbolised by a green cell border
Practice Jupyter Notebook
Jupyter notebook shortcuts: Practising a few minutes to learn specific shortcuts of the Jupyter Notebook keyboard will help an individual be a more efficient and experienced Python developer. These keyboard shortcuts are some of them that most professional developers found very useful.
These are the shortcuts that professionals practice in their daily work. If one still necessitate something that is not mentioned in these articles, then they can discover it in the keyboard shortcuts dialogue (H). One can also add more shortcuts or edit existing ones from the Help > Edit Keyboard Shortcuts connect in the menu bar. Clicking the loop will begin a dialogue. At the bottom of the tab, there are rules for editing or adding shortcuts. One needs to use hyphens – to designate keys that should be pressed at the same time. For example, a person added a shortcut Ctrl-R for the restart kernel and ran all cells command.
These shortcuts of the Jupyter Notebook are created on my Github repo that one can download and apply to practice these keyboard shortcuts.
Note: that the shortcuts mentioned below are for Linux and Windows users. Nevertheless, for Mac users, they’re distinctive buttons for Ctrl, Alt and Shift:
- Ctrl: command key ⌘
- Alt: option ⌥
- Shift: Shift ⇧
These keyboard shortcuts are for Mac OSX and Jupyter version 4.1.0. For most below-mentioned shortcuts, one can replace cmd for ctrl for Linux or Windows. Or, one can utilise the H keyboard shortcut in Linux or Windows to confirm the appropriate keyboard shortcuts for those operating systems.

While in Command Mode
- Press A to insert a new cell preceding the current cell,
- Press B to insert a new cell underneath.
- Press M to modify the current cell to Markdown,
- Press Y to transform it back to code
- Press D + D (press the key twice) to delete all the selected current cell
- Press Enter will take the programmer from the command mode terminal into edit mode for the assigned cell.
- Press Shift + Tab will display the user the Docstring (documentation) for the object the person has just typed in a code cell – they can continue pressing this shortcut to toggle through some modes of documentation.
- Press Ctrl + Shift + will actually split the current cell into two from where the person cursor is placed at that time.
- Press Esc + F helps to find and replace the code of the user but not the outputs.
- Press Esc + O to toggle all of the cell output.
Select Multiple Cells
Jupyter notebook shortcut: Press Shift + J or Shift + Down selects the next cell in a downwards direction. One can also select cells in an upwards direction by simply pressing Shift + Up or Shift + K.
Once cells are selected, one can then copy / cut / paste / run / delete them as a batch. This is convenient when one needs to move specific parts of a notebook.
One can also utilise Shift + M to merge multiple cells.
Edit Mode
One can press Enter to enable to be in Edit Mode

Text Snippets
Text snippets enable a person or a professional coder to keep things consistent and save time typing.
For any text snippets, the usual recommendation is Textexpander which is exclusively made for Mac OSX only. However, Windows users, can use PhraseExpress and in the past which serves well too.
For quick imports for all favourite packages of an individual user:
Constantly importing the same packages or/and forget what that package that a person always uses is named. People like to store their default imports in a snippet. The article recommends individuals create a similar snippet and tune it to their preferences.
