I dug into this some more, and this code is what's causing the shortcuts
to be ignored:

    if (i == LEN(mappedkeys)) {
        if ((k & 0xFFFF) < 0xFD00)
            return NULL;
    }

For whatever reason, kmap is written so that anything that falls below
0xFD00 will never make it to the for loop that looks up mappings in the
"key" array. I'm not providing a patch because I don't know what the
rationale behind this decision was, and my personal copy of st is very
out of sync with the upstream repo.
