The Problem

An operation I do a lot is to highlight/select code on the editors and then paste it on the integrated terminal to execute it. While I got pretty fast at using Ctrl + c, Ctrl + backtick, Ctrl + Shift + v and Enter, it's very annoying and repetitive. Is there a way to configure a macro or shortcut for this?

A Solution (failed) Attempt

This Github thread and this StackOverflow Question show how to create a shortcut to toggle between different Integrated Terminals. I would like for something similar to happen in my case (I used Ctrl + Shift + u in the example below), e.g.:

[
    { 
        "key" : "ctrl+shift+k", 
        "command" : "workbench.action.terminal.focusNext" 
    },
    { 
        "key" : "ctrl+shift+j", 
        "command" : "workbench.action.terminal.focusPrevious" 
    },
    { 
        "key" : "ctrl+shift+u", 
        "command" : "ctrl+c+ctrl+`+ctrl+shift+v+enter" 
    },
]
