The article “Jupyter Notebook Shortcuts” first appeared on AlgoTrading101<\/a> blog.<\/em><\/p>\n\n\n\n

Notebooks are tools that allow us to use markdown along with our code, to improve readability and really add to that storytelling aspect of a project. JuPyteR\u200a\u2014\u200ashort for Julia,Python and R\u200a\u2014\u200ais probably the most popular notebook used and comes as part of the standard anaconda installation process.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

When you click on the Help<\/strong> tab of Jupyter\u2019s taskbar you\u2019ll see a list of references, the user interface tour and much more. Included in this would be the Keyboard Shortcuts <\/em>menu which lets you view all of the possible ways to quickly execute common track-pad tasks using your keyboard. Today we\u2019ll be talking about the most useful of these options.<\/p>\n\n\n\n

The Keyboard Shortcuts<\/em> menu is divided into 2 categories called Command Mode<\/strong> and Edit Mode<\/strong>. We will be keeping this structure as we move on to the main event in our article.<\/p>\n\n\n\n

Before we begin it is important for Mac users to keep the following conversion in mind:<\/em><\/strong><\/p>\n\n\n\n

Ctrl\u200a\u2014\u200a\u2318 <\/em><\/code>command key<\/em><\/p>\n\n\n\n

Shift\u200a\u2014\u200a\u21e7 <\/em><\/code>Shift<\/em><\/p>\n\n\n\n

Alt\u200a\u2014\u200a<\/em>\u2325<\/code> option<\/em><\/p>\n\n\n\n

Edit Mode<\/h3>\n\n\n\n

To enter the edit mode, press the Enter<\/code> key. These shortcuts may seem very familiar to the ones you may use in other text editors and general computer use.<\/p>\n\n\n\n

Ctrl-S<\/code>: Save and Checkpoint <\/p>\n\n\n\n

Tab<\/code>: code completion or indent<\/p>\n\n\n\n

Indenting Selected Text<\/em><\/strong><\/p>\n\n\n\n

Ctrl-]<\/code>: indent Ctrl-[<\/code>: indent to the left (dedent)<\/p>\n\n\n\n

More Text Editing<\/em><\/strong><\/p>\n\n\n\n

Ctrl-A<\/code>: select all Ctrl-Z<\/code>: undo<\/p>\n\n\n\n

Ctrl-\/<\/code>: comment Ctrl-D<\/code>: delete whole line<\/p>\n\n\n\n

Ctrl-U<\/code>: undo selection Insert<\/code>: toggle overwrite flag<\/p>\n\n\n\n

Go To<\/em><\/strong><\/p>\n\n\n\n

Ctrl-Home<\/code>: go to cell start Ctrl-Up<\/code>: go to cell start Ctrl-End<\/code>: go to cell end<\/p>\n\n\n\n

Ctrl-Down<\/code>: go to cell end Ctrl-Left<\/code>: go one word left <\/p>\n\n\n\n

Ctrl-Right<\/code>: go one word right <\/p>\n\n\n\n

Delete \/ Redo<\/em><\/strong><\/p>\n\n\n\n

Ctrl-Backspace<\/code>: delete word before Ctrl-Delete<\/code>: delete word after<\/p>\n\n\n\n

 Ctrl-Y<\/code>: redo Alt-U<\/code>: redo selection <\/p>\n\n\n\n

Run<\/em><\/strong><\/p>\n\n\n\n

Shift-Enter<\/code>: run cell, select below Ctrl-Enter<\/code>: run selected cells<\/p>\n\n\n\n

Alt-Enter<\/code>: run cell and insert below<\/p>\n\n\n\n

Split<\/em><\/strong><\/p>\n\n\n\n

Ctrl-Shift-Minus<\/code>: split cell at cursor<\/p>\n\n\n\n

Command Mode <\/h3>\n\n\n\n

To enter the command mode, press the Esc<\/code> key.<\/p>\n\n\n\n

Enter:<\/code> enter edit mode F<\/code>: find and replace <\/p>\n\n\n\n

Insert Cells<\/em><\/strong><\/p>\n\n\n\n

A<\/code>: insert cell above B<\/code>: insert cell below<\/p>\n\n\n\n

Run and Insert Cells<\/em><\/strong><\/p>\n\n\n\n

Shift-Enter<\/code>: run cell, select below Alt-Enter:<\/code> run cell and insert below <\/p>\n\n\n\n

Change Cell Type<\/em><\/strong><\/p>\n\n\n\n

Y<\/code>: change cell to code M<\/code>: change cell to markdown R<\/code>: change cell to raw<\/p>\n\n\n\n

Change Markdown Header Size\u200a\u2014\u200aUp to 6 sizes with 1 being the Largest<\/em><\/strong><\/p>\n\n\n\n

1<\/code>: change cell to heading size 1 2<\/code>: change cell to heading size 2 <\/p>\n\n\n\n

Select Multiple Cells<\/em><\/strong><\/p>\n\n\n\n

Shift-Up<\/code>: extend selected cells above Shift-Down<\/code>: extend selected cells below<\/p>\n\n\n\n

Cut, Copy and Paste<\/em><\/strong><\/p>\n\n\n\n

X<\/code>: cut selected cells C<\/code>: copy selected cells<\/p>\n\n\n\n

Shift-V<\/code>: paste cells above V<\/code>: paste cells below<\/p>\n\n\n\n

Merge Cells<\/em><\/strong><\/p>\n\n\n\n

Shift-M: <\/code>merge selected cells, or current cell with cell below if only one cell is selected<\/p>\n\n\n\n

Z<\/code>: undo cell deletion O<\/code>: toggle output of selected cells<\/p>\n\n\n\n

The keystrokes for the following are misleading. We have listed them as they are in the keyboard shortcut menu, however it is important for you to remember that the actual process does NOT include the comma. So for deleting selected cells you would actually type <\/em><\/strong>DD<\/code> .<\/p>\n\n\n\n

D,D<\/code>: delete selected cells I,I<\/code>: interrupt the kernel 0,0<\/code>: restart the kernel <\/p>\n\n\n\n

Miscellaneous<\/em><\/strong><\/p>\n\n\n\n

H<\/code>: show keyboard shortcuts Q<\/code>: close the pager<\/p>\n\n\n\n

Shift-L<\/code>: toggles line numbers in all cells, and persist the setting<\/p>\n\n\n\n

Shift-Space<\/code>: scroll notebook up Space<\/code>: scroll notebook down<\/p>\n\n\n\n

Aside<\/h4>\n\n\n\n

The command palette runs any command by name. To open the command palette, use Esc<\/code> to enter command mode and then press P<\/code> .<\/p>\n\n\n\n

Conclusion<\/h3>\n\n\n\n

Shortcuts can prove quite useful in helping you to maintain focus by avoiding some extra scrolling with your mouse. In fact Brainscape claims that just by using keyboard shortcuts alone, you can increase your overall productivity by 3.3%, saving yourself a total of 64 wasted hours in a year. Whether you believe this or not, at the very least using shortcuts definitely helps you cut-down on using that annoying track pad, while making you look super cool<\/strong> at the same time.<\/p>\n\n\n\n

I kid, but until next time, do enjoy the shortcuts that you\u2019ve learned today!<\/p>\n\n\n\n
