什么是emacs中的＆键绑定？

Question

例如，yasnippet提供命令const inventoryArray = [{"name":"pizza","category":"food","unique":"no","amount":12},{"name":"bow","category":"weapon","unique":"no","amount":1},{"name":"pizza","category":"food","unique":"yes","amount":1}] const props = ['name', 'category', 'unique', 'amount'] const result = props.map(p => [...new Set(inventoryArray.map(o => o[p]))] ) console.log(result)，该命令绑定到yas-new-snippet。我不明白这是什么意思。这并不意味着先按Ctrl-C，然后再按Ctrl-n（应为C-c & C-n）。这也不意味着先按Ctrl-C，再按n。正确的输入方式是什么？

Answer 1

只需输入 C-c ，＆和 C-n 。
