Problem: Incorrect Letters appear when keys are pressed.
Sometimes a Chromebook lists something other than"US" in the bottom right corner. When you see this, it means the Chromebook Keyboard has been changed from the US Standard keyboard to a different style of keyboard. When this happens, some keys will not make the letter/symbol you expect to appear.
Solution:
There are 2 solutions to the above problem.
Change via Keyboard Shortcut: To return the Chromebook keyboard back to US settings, press Ctrl + Spacebar. This keyboard combination switches back and forth between US and Colemak keyboards.
Change via Language icon:
Click the picture in the bottom right-hand corner of your Chromebook screen(1) and click the icon that says “Keyboard ▼”
(1) 
Under the options here, switch back to the US keyboard.
