Minimum working patch to add AltGr + "#", "{", "[", "|", "`" and "\" tested on French keyboard

[VigibotDev]

On French keyboard, I can't write the backslash, it back delete instead :

AltGr combined with [3] to [8] keys do not work
-> These is no "#", "{", "[", "|", "`" and "", this is anoying:(

But :
AltGt + 1 "~"
AltGt + 9 "^"
AltGt + 0 "@"
AltGt + ) "]"
AltGt + = "}"

Are OK

I found the bug :D
I added "if (ev.altKey && ev.ctrlKey) {"
before "if (ev.ctrlKey) {"
and I replaced with "} else if (ev.ctrlKey) {"

To work this part of code need "ev.ctrlKey" without "ev.altKey" or reciprocally

There is another equivalent code : "ev.ctrlKey and not ev.altKey" / "ev.altKey and not ev.ctrlKey" for the two "if".

Diff with current master :

<       if (ev.altKey && ev.ctrlKey) {
<
<       } else if (ev.ctrlKey) {
---
>       if (ev.ctrlKey) {

Working code :

    // F11
    case 122:
      key = '\x1b[23~';
      break;
    // F12
    case 123:
      key = '\x1b[24~';
      break;
    default:
      // a-z and space
      if (ev.altKey && ev.ctrlKey) { // Added

        // Empty

      } else if (ev.ctrlKey) {
        if (ev.keyCode >= 65 && ev.keyCode <= 90) {
          // Ctrl-A
          if (this.screenKeys) {
            if (!this.prefixMode && !this.selectMode && ev.keyCode === 65) {
              this.enterPrefix();
              return cancel(ev);
            }
          }
          // Ctrl-V
          if (this.prefixMode && ev.keyCode === 86) {
            this.leavePrefix();
            return;
          }
          // Ctrl-C
