Unfortunately I’m a 2-fingered typist, and for years have had to correct run-together words from not hitting the space bar or hitting an “m” or ‘n” when intending a space. It was a constant hassle.
So recently a cut a small piece of 1/8th wood, allowing for an overlap. I attached it with YMHB (very strong) double-stick tape and voilá, no mas problemas.
Part of the problem for me for me is that space bars on keyboards are flush with other keys; with this setup, the space bar is not only elevated, but I can hit it farther out.
