Multiple cursors in vscode
One of the best features in vscode is the Multiple cursors one.
Imagine you've a bunch of lines where you need for instance remove the first two characters. Each lines starts with '//' and you wish to remove them but only there (a search & replace can't be used).
Or, for another example, you must enclose each line in double brackets.
With vscode, it's ultra-simple: multiple cursors.
