Keyboard without AltGr - now what?

Recently I found myself using temporarily a keyboard without "right Alt" key, also called "AltGr" (graphical Alt). However I needed that to work to enter characters in the locale I am in.
So I thought: is there any hope? SharpKeys to the rescue!

TL;DR

I ended up with single entry in the Windows Registry, with necessary system restart afterwards. Then to my surprise IT JUST WORKED! ^(TM) 😁

Following is the exported registry data with Scancode Map key:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout]
"Scancode Map"=hex:00,00,00,00,00,00,00,00,02,00,00,00,38,e0,5d,e0,00,00,00,00

Windows 10 JumpListItems_Maximum

In the Registry Editor, use the left sidebar to navigate to the following key:

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced

Right-click the Advanced folder and choose New > DWORD (32-bit) Value. Name the new value JumpListItems_Maximum and then double-click the value to open its properties window.

In the value’s properties window, select “Decimal” under Base and then enter the number of recent items you want your jumplists to show in the “Value data” box. We’ve found that 15-20 is a pretty good number that still lets the whole jump list show on most displays.
