Taking a Shortcut When Coding Your Arduino Project

By John Nussey

Part of Arduino For Dummies Cheat Sheet

After you have built your Arduino project, you may have many hours ahead of tweaking the code until it’s perfect. It’s handy to know a few shortcuts to speed up the process. Here are the some of the most useful:

Windows/Linux Mac OS Action
Ctrl+N Cmd+N Open new sketch.
Ctrl+O Cmd+O Open existing sketch.
Ctrl+S Cmd+S Save sketch.
Ctrl+Shift+S Cmd+Shift+S Save a sketch with a new name.
Ctrl+R Cmd+R Compile and verify a sketch. Handy for checking the grammar of your
code without uploading the sketch.
Ctrl+T Cmd+T Auto format. Adjusts the alignment and spacing of your code to
improve the legibility (but also undoes your own formatting if
you’re arranging your sketch in a unique way).
Ctrl+Z Cmd+Z Undo the last change to code.
Ctrl+Shift+Z Cmd+Shift+Z Redo the last change to code.
Ctrl+/ Cmd+/ Comment/uncomment the selected code. Useful for quickly commenting
code out. Commenting a section of code means that it is not
uploaded to the board, so you can use comments to quickly switch
among different sections of code without having to delete
them.
Ctrl+Shift+F Cmd+Shift+F Find reference page for selected code term. If you’re
unsure about a highlighted term in your sketch (such as void, int,
or pinMode), simply select that term and use this shortcut to be
sent to the latest reference page.
Ctrl+U Cmd+U Upload the sketch to the Arduino board.
Ctrl+Shift+M Cmd+Shift+M Open the serial monitor.
Ctrl+K Cmd+K Open sketch folder.
