Macro like keybindings

When creating keyboard shortcuts, it would be nice if you could pass an array of commands (to execute like a macro) that would run the commands in that order.

So take this for example:

{
    "key": "ctrl+s",
    "command": [
        "editor.action.format",
        "editor.action.trimTrailingWhitespace",
        "workbench.action.files.save"
    ],
    "when": "editorTextFocus"
}

It would format the file, remove trailing white space then save the file.

2019 is asking why this feature is still not added yet! @sandy081, @joaomoreno and others working on the keybindings, this Issue was opened in 2015, that’s four full years of development time not spent adding an extremely useful and seemingly simple feature. The back end of the keybindings API could just concatenate the listed commands and run them one after another. Please add this, there is no official fix besides using extensions for a very basic feature!
