Question

I use slash a lot in writing notes, and it always activates the block list. Can I disable it or change the function with another shortcut?

Answer 1

Doesn't seem possible as-is: https://twitter.com/notionhq/status/1130594925018353664?lang=en

If you are using Notion in a browser, you could add this CSS in Stylish:

[contenteditable]:empty:before {
    display: none;
}

Answer 2

Also you can use ESC to close the menu and if you keep typing, it will be closed automatically.
