1. it returns strings. If you use ncurses form drivers these take 
integers. So one has to convert the value sent to an int to avoid 
errors.

So typically in the start of the press method, I have done:

    ret = ret[0] if ret.length == 1
    ret = 32 if ret == 'space'

Even then one has to watch out for others that are not single length 
tab/return/bs/ etc.... will have to check for others. Some of these are
separately handled in the case, such as tab and return so thats okay. 
Others such as backspace and delete etc which were passed straight to 
the driver, need to be watched out for.

2. You check for @stopping? inside the while char loop immediately after 
while.
To me this means that after the user has entered the Exit key, he still 
has to press one more key to actually exit. I've put the break before 
the end of the loop. Would like you to confirm this.
