I’m currently using Vintage mode and I was wondering if there is any key binding to scroll through the file like vim’s ctrl + D, ctrl + U, etc

Ctrl+D and Ctrl+U work just fine in Vintage mode for me.

On Windows you have to enable the use of Ctrl keys:

In Preferences/Settings - User, add this:

"vintage_ctrl_keys": true

The downside is that Ctrl+D will then shadow the very handy “Add Selection” command, though.

You will find an explanation of available Vintage settings in* Packages/Vintage/Preferences.sublime-settings*.

@ Key Bindings - User

	{ "keys": "ctrl+d"], "command": "find_under_expand",
		"args": {"forward": true},
		"context": {"key": "setting.command_mode"}, {"key": "setting.vintage_ctrl_keys"}]
	},
