ctrl+l, test, shift+enter, ctrl+.

Is it correct? shift+enter instead of enter.
ctrl+l, test, shift+enter, >, test, enter, backspace, shift+enter,
test, enter, backspace, ctrl+shift+., ctrl+shift+.

I think it's ok, it's better than using blockquote for the wrapping list

shift+enter is different from enter
enter will generate a tag p, ctrl+shift+. change the block element to blockquote. shift+enter is a tag p, and can not insert blockquote.

Ok.
Which one is right?
ctrl+l, test, shift+enter, ctrl+.

or

I expected like when ctrl+shift+.

and the event.key at mac is . but > at windows.

blockquote is a block element, shift + enter cannot create a new block element, and therefore cannot create a new blockquote.
It is recommended that you press shift+enter, shift+enter, ctrl+.

thanks for your reminder

windows can not support ctrl+>, maybe change hotkey 😢

use both like

(blockElement && isCtrl(event) && event.shiftKey && (event.key === "." || event.key === ">"))

Thanks, I have refactored it to ctrl+: and ctrl+shift+:
