Ctrl + Alt + Up (and Down) do not seem to be assigned to any Windows function, yet they are not passed correctly by Remote Desktop. Can this be fixed?
Tested on Windows 8.
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.
I had this same problem, but using different mstsc didn't seem to help. This post:
suggested using hotkeys. So I tried making a simple AutoHotkey (AHK) script. I was able to get this working. Save the following:
in a .ahk file in the computer I am connecting to, then run the file. The command Ctrl+Alt+PgUp and Ctrl+Alt+PgDn produce the multi-line selection. The only thing I don't really like about it is that the arrows are usually closer to my hands when typing than the PgUp and PgDn buttons, but I still prefer it over the mouse.
I have same problem with CTRK + ALT + UP or DOWN. It looks like default RDP client is broken. Well done Microsoft.
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.
