One commonly-used keyboard option not found on most Chromebooks is the Delete key—a casualty of smaller, redesigned devices. By using the magic of keyboard shortcuts, you can still simulate the behavior of a Delete key on Chrome OS. Here's how to create a Chromebook delete key function, as well as several others.
How to Delete on Chromebook
To mimic the Delete key's functionality on Chrome OS, you can use the following keyboard shortcut: Alt+Backspace. This key combo can be pressed for a number of different reasons, such as deleting a file or erasing the character to the right (or in front of) your blinking cursor.
In contrast, the Backspace key is essentially the Chromebook Delete key and you can use it without any additional keys to delete the character to the left (or behind) your cursor.
In other instances, such as when you're dealing with files or even a selected block of text, you can right-click the item you wish to remove, then select Delete from the context menu.
Other Chromebook Shortcuts
In addition to Delete, there are other keys found on traditional keyboards that may not be available on a standard Chromebook. Thankfully, most of these missing keys can also be mimicked by using the following shortcuts.Home: Ctrl+Alt+Up ArrowEnd: Ctrl+Alt+Down ArrowPage Up: Alt or Search+Up ArrowPage Down: Alt or Search+Down Arrow
To see a full list of keyboard shortcuts avaiable in Chrome OS, grouped by category, select the View keyboard shortcuts option found toward the bottom of the Keyboard settings page.
How to Create Custom Keys on Chromebook
While you can't create a custom Delete key on your Chromebook, you do have the option of mapping some other functions to a number of existing keys.
Log into your Chromebook, if necessary.
Click the Time indicator in the lower right-hand corner of the screen.
When the pop-up window appears, click Settings, represented by a gear icon and found in the upper right-hand corner.
The Chrome OS Settings interface should now be displayed. Click Device, located in the left menu pane.
The Chromebook Keyboard settings will now be visible. Toward the top of this screen are Search, Ctrl, Alt, Escape, and Backspace, each accompanied by a drop-down menu. You can modify what these individual keys do when pressed by selecting a different value from the respective key's menu. So, for example, if you don't use the Search key often, but miss having a Caps Lock key available on your Chromebook, simply click its drop-down menu, then click Caps Lock.
Once satisfied with your updates, click the X in the upper right-hand corner to close the Settings interface. Your new keyboard assignments should take effect immediately.
