I see that the get_key() function allows for the program to get the next key
pressed without waiting. How do I assign that key's identity (a numeric
value I'm guessing) to a variable so that I can manipulate it?
while get_key() = -1 do
bla bla bla
end while
But how do I take whatever key was pressed and use it?

You can answer your own question! You wrote:
get_key() = -1
which means get_key() is a function. All you have to do is turn it around...
variable = get_key()

For a practical demonstration of
this, try:
ex ed c:\euphoria\bin\key.ex
at the dos prompt.
(assuming you have EU on drive C)

Try the following code:
integer key
key = get_key()
while key = -1 do
key = get_key()
end while
printf(1, "The code of the key pressed was: %d", key)
I hope I didn't make any mistakes since I haven't tested it!
