I had to download a key remapper once because I broke my arrow keys playing Happy Wheels. Well the down arrow key specifically. Idk you could try to find one and remap the right alt key to work as spacebar or something.
I think its easier for the person typing because you know what you're typing so its easy to distinguish which words are which. While the reader has no idea whats actually being written so it takes a minute to figure out where each word actually starts and stops.
