Backslash problem on a Logitech K750 keyboard

[norway2014]

Hi. I have on a key on a keyboard the following: backslash, question mark and the plus sign. But, I can not get the backslash to work. The keyboard is qwerty and Norwegian layout. Anyone got a clue?

Hello and welcome Norway mate seems to me to be a situation where you needto hold a designated key down to get the backslash.

Much like CTRL+V is paste.

Now I would suggest opening a Word documentand then start hitting CTRL or ALT or FNor the windows flag key and the hit the backslash key and see what happens.
The alternative is to get another keyboard - perhaps the function key is not working with the backslash one.

Just found this and wondered why I hadn't thought of it before

That's strange.
I have tried every possible combination of keys.
No Luck yet.

Why?
If I use another keyboard with a "simpler" backslash button it works.
But, I want to use this one.

Well just those checks will at least test out any corrupted and / or bad sectors in the OS. Doesn't take long and is just a way of eliminating anything I use when things get a bit out of whack with my machines. My reasoning is if it was working before then something has happened to the machine to put it out of kilter.
But if you think it will not help then the choice is yours
Frankly it could be just about anything form the keyboard switches to malware.
