Why does the IME give me "←" when I type "zh"? I accidentally typed "zh" using the Japanese IME on macOS Sierra. Surprisingly, "zh" turned into a "←" character! Why does it do this? I would have expected it to produce just "zh", like it does with other two consecutive consonants: "kr" is "kr", "mn" is "mn". Why is "zh" a left arrow? I did some guessing and thought that the "h" must stand for , that's why it's a left arrow and not a right one. Then I tried "zm", thinking that it would give me a right arrow because "m" stands for , it _didn't_. I am so confused. What does "zh" stand for? Why a left arrow? How do I do a right one? Note: the left arrow is U+2190 "LEFTWARDS ARROW"

I can't tell you about the wherefore but that seems to be a shortcut associated with the letter z + hjkl-directional keys. Moreover this doesn't work with all IME (but it can be reproduced with Google IME, you can try that on Google Translate website)

I dug a bit more and here a list of keys that goes with the `z`-mod key.

* ZH ←
* ZJ ↓
* ZK ↑
* ZL →
* Z, ‥
* Z. …
* Z/
* Z[
* Z]
* Z-
