Sublime has many options to close tabs such as closing the current tab or closing all tabs to the right or closing other tabs. What would be nice is to have an option to close all tabs.

This functionality already exists under File > Close All Files but there is no shortcut for it.

Here’s how you add a shortcut to close all open files:

{ "keys": ["shift+super+ctrl+w"], "command": "close_all" }

Now you can close all open files with “shift+super+ctrl+w”.
