Taking a screenshot to show us the problem

When something goes wrong on screen, a screenshot is often the fastest way to explain it. Error messages contain codes that tell us exactly where to look, and a picture of the whole window shows us things you might not think to mention, such as which account you are signed in with.

Windows

Press the Windows key + Shift + S together. The screen dims and you can drag a box around the part you want. The picture is copied, so you can paste it straight into an email with Ctrl + V. A small notice also appears in the corner; click it to mark up or save the image. To record a short video of a problem that only happens when you click through several steps, open the Snipping Tool and choose the video option.

Mac

Press Command + Shift + 4 and drag a box around the area you want. The screenshot is saved to your desktop. Press Command + Shift + 5 instead for options, including recording the screen.

iPhone and iPad

Press the side button and the volume-up button at the same time. On older models with a home button, press the home button and the side or top button together. The screenshot goes to the Photos app, where you can share it by email.

Android phones

On most Android phones, press the power button and the volume-down button together. Some phones also offer a screenshot option when you hold the power button. The image is saved to your gallery.

Before you send it

Have a quick look at what else is in the picture. If a password, a customer's personal details or a private message is visible, crop it out or cover it before you send it. We never need to see a password, and we will never ask for one by email.

Then attach the image to your email to hello@bitnode.tech along with a sentence or two about what you were doing when it happened.
