Mac OS X "Invalid key shortcut sound" on ⌃⌘↓

[varkor]

• VSCode Version: 1.20.1
• OS Version: 10.11.6

Steps to Reproduce:

1. Press ⌃⌘↓ in the text editor. The "invalid key shortcut" sound will be played. (This is also the case for ⌃⌘← and ⌃⌘→.
2. Press ⌃⌘↑. The "invalid key shortcut" sound will not be played.

There's clearly something going funny here, because up and down have different behaviour. These sounds play even if they are valid key shortcuts.

Yeah this also affects move to next/previous terminal pane keys I found recently.
