Swap Alt and Control keys

One of the first things a MacBook user might do on a Chromebook is mistakenly hit the Alt key instead of the Control key because on a MacBook keyboard, you use the Command key for many keyboard shortcuts such as cut, copy and paste. And a MacBook's Command key is directly to the left of the spacebar, just as the Alt key is on a Chromebook. Thankfully, you can reassign the Alt and Control keys on a Chromebook. Just click your account profile picture in the bottom-right corner and then click the gear icon. From the Settings window, scroll down to the Device section and click Keyboard and then assign the Ctrl key as Alt and the Alt key as Ctrl.

Set up Linux (Beta) on your Pixelbook

• Select the time in the bottom right to open your status area.
• Select Settings (gear icon)
• Under "Linux (Beta)," select Turn On

Once the Linux (Beta) is enabled, the Terminal app will appear in the launcher.

boto3 quick hands-on

This documentation aims at being a quick-straight-to-the-point-hands-on AWS resources manipulation with [boto3][0].

First of all, you'll need to install [boto3][0]. Installing it along with [awscli][1] is probably a good idea as

• [awscli][1] is boto-based
• [awscli][1] usage is really close to boto's
