Written for Chinese
w moves by real Chinese words, found with a dictionary rather than spaces. Sentences, clauses and Chinese brackets are things you can select and change.
Helix and vim keys, cursor motions by Chinese word, vertical editing, and the Yume input method built in.
yumete works the way helix does. Every move leaves a selection: w walks forward one word and selects the word it walked over, and x selects a line. You see the text you are about to change before you change it, and then d deletes it, c replaces it and y copies it. The character under the cursor is part of the selection, so what the block covers is what d takes.
Where yumete differs from helix, it is mostly for people who write in 漢字. Editors made for English find words by spaces, and Chinese has none, so w here asks a dictionary. English is only written across the page, and Chinese is also written in columns, so the page can turn. And an input method that sits outside the terminal cannot tell Normal mode from Insert mode, so this one is inside the editor. If your fingers know vim rather than helix, see Coming from vim.
