RuskDesk keyboard mapping is broken

[hcarsten]

Bug Description

I used use a Mac to connect to a Win10 Box. I use the Win10 box as a jumper to other machine e.g. using putty to ssh into other box.

on the putty I often get the "unbound key" message. This is coming from the nano editor in the ssh terminal, but actually I never saw this.
Then sometimes the systems systems to detect a shortcut, so suddently the "Edge Browser" opens and open a couple of times the "office login page".

Actually the remote box has a "Sophos FW" Solution but IT-Services said, it should be deactivated.

You have the "Keyboard Mode"-Button, anyway I do not understand what are the various options and which setup is the one I need ?

How to Reproduce

login on the box

Expected Behavior

keyboard should work
