I currently have these in my user keybindings.json:

[
    { "key": "ctrl+down", "command": "editor.action.moveLinesDownAction",
                             "when": "editorTextFocus" },
    { "key": "ctrl+up",   "command": "editor.action.moveLinesUpAction",
                             "when": "editorTextFocus" }
    { "key": "ctrl+i",    "command": "expandLineSelection",
                             "when": "editorTextFocus" },
]

ctrl+up and ctrl+down are standard are used in atom (similar product to vscode) and used as ctrl+shift+up and ctrl+shift+down in sublime text. Any chance these can at least be bound to something?

Also regarding ctrl+l, it is the default for selecting a line in atom editor as well as sublime text. Could this be changed from ctrl+i to match this?
