On mac, holding shift to type certain characters(like %) doesn't work

[CarsonML]

Sometimes holding shift works fine, like for all letters and :, but for others, like %, trying to type it(shift + 5 in this case) just types the original character and not the shifted version(5 in this case)

#83 contains two separate issues, of which one is fixed. I will reopen this issue, since it contains only the remaining one.
