Keyboard shortcut to comment lines in Sublime Text 3

Question

In Sublime Text 2 it was possible to comment out a line or a block of lines with Ctrl+/ and Ctrl+Shift+/. According t

Answer 1

On my mac the shortcut is ⌘cmd + / which makes multi line comment but as single lines:

// if ($username && $password) {
//  echo "You are good to go";
// } else {
//  echo "Fields cannot be blank";
// }

OR

⌥ alt + ⌘cmd + / and it's result is overall comment, from beggining of the selection to the end.

/*
if ($username && $password) {
    echo "You are good to go";
} else {
    echo "Fields cannot be blank";
}
*/
