💡 Add backward key navigation for options

[harshsinghatz]

After the typing practice, we get a graph of our performance and multiple options ( such as Next test, Repeat test, Practice words, etc ) which we can navigate forward through the "tab" button but there is no way of navigating backward.

My Recommendations for the keys:

• "Backspace" button
• "shift" button

Why should we implement this?

• As monkeytype is typing oriented application it is very suitable
• It's easier for the typist to navigate

I believe shift + tab is the default in every browser for moving focus backwards.

My bad didn't know about that 🙌
