CustomShortcuts

数式を書く機会が多いので[$ ]の入力のショートカットをつけた

code: script.js

document.addEventListener('keydown', (e) => {

if (!e.altKey) return

e.preventDefault();

e.stopPropagation();

const textarea = document.getElementById("text-input")

const reactKey = Object.keys(textarea).find((key) => key.startsWith("__reactFiber"));

const cursor = textareareactKey.return.return.stateNode._stores0

//console.log(cursor)

switch (e.key) {

case "=":

document.execCommand('insertText', null, '$ ')

cursor.goLeft();cursor.goLeft();

break;

case ".":

cursor.goWordTail()

break;

case ",":

cursor.goWordHead()

console.log("head")

break;

}

})
