Hi JasWV,
Good day! This is Jhakesong and I will be happy to assist you with this.
I am sorry to hear about the inconvenience. Here's how you can highlight a text in windows 10 just by using your keyboard.
- Go to the starting point of the text you want to highlight
- Hold down the shift key.
- While the shift key is held down, press the right arrow key to highlight the text going to the right side.
- Once you have covered the text you want to highlight, let go off the shift key.
Note: If you want to highlight a whole line of text, move to the starting point, hold down the SHIFT key, press the END key from your keyboard then let go of the SHIFT key.
Let me know how it goes. Have a great day!
