Needs to be a key for “ion” thus you just type nat and then the hotkey and wind up with nation in 4 key strokes.
Maybe 5 keys with top combinations for increasing throughput. Potentially a key for really long words like international. If I just hit windows key + 4 and it typed international might not be all value out. Potentially more value with less combos, specific key that always typed the word international without reliance. Maybe control ii in repeated fast like a double click. Or maybe a word hotkey like shift. Word + I = international, Word + P = potential
Potential for keyboards for specific programming languages. Word + n = null (useful for java), Word + s = System, Word + c = ConcurrentHashMap
Word + p = push to production bypassing staging, QA, and dev?
