Cannot type in $ signs on a Swedish EU-keyboard inside jshell

I have a problem to follow along in the video from the point where $3 ==> false, because I cannot type in $ without starting a full thread dump process. To type in a $ it's Alt Gr+4 on a Swedish keyboard.

The process starts like this:

jshell> 2017-02-21 13:20:28                                                                           
Full thread dump Java HotSpot(TM) 64-Bit Server VM (9-ea+139 mixed mode):

        - parking to wait for  <0x00000000f8152550> (a java.util.concurrent.SynchronousQueue$TransferS

and goes on for thousands of lines.

Hi Richard! I also live in Sweden and use a Scandinavian keyboard layout. And I really hope you are doing this from a Windows system, because I've yet to find a way to make it work on my Mac. But you can enter an "alt code". In this case for the dollar sign, you hold down alt and then press 3 6. Alt + 36. It will pause for a second, but then it will write out the dollar sign.

You can find a full list of "alt codes" here. I hope this helps! If you happen to be doing this on a Mac let me know and I'll try and do some further research! :sparkles:

Thanks for the answer! Luckily I work in Win 10 at the moment (will have to figure it out on my Macbook) but now I can at least get further in the exercises :)

Note to others: This will only work with the Numpad.
