Remote desktop does not pass Ctrl-Alt-Up (and Down)

I have same problem with CTRL + ALT + UP or DOWN. It looks like default RDP client is broken.

As an alternative try Remote Desktop software from Microsoft Store https://www.microsoft.com/en-us/p/microsoft-remote-desktop/9wzdncrfj3ps?activetab=pivot:overviewtab

It is not ideal. It has this annoying blue bar at the top of screen in full screen mode. It looks like those programmers don't use their application at all. All web browsers have tabs at top bar now and this annoying bar appears on top of them. Well done Microsoft once more. However, at least keys are send to the remote computer.

I just changed the keyboard shortcut in my editor.

I am using Visual Studio Code (VS Code) on a remote machine and Ctrl+Alt+↑ and Ctrl+Alt+↓ to insert a cursor above and below, respectively. I just went into VS Code and changed the key binding to the key chord Ctrl+↑ Ctrl+↑ and Ctrl+↓ Ctrl+↓, respectively. So I have to push the up or down arrow more times, but at least that works and is quicker than the mouse.

This is done in VS Code by Ctrl+k Ctrl+s, then you can search for "cursor" and you'll see "Add Cursor Above" and "Add Cursor Below", which are the settings to modify.

I have recently run into this very annoying problem. My solution was to use another version of mstsc.exe. The problematic version was 6.3.9600.16415. Replaced with 6.1.7601.17514 and everything is fine. Haven't checked other versions.
