"US International" keyboard definition: solution found!
 

I use a standard US keyboard. In my language (Dutch) I need the dead keys of the "US International" keyboard definition. This option does not show in the control panel.

After delving deep into the system, I finally found out that I should select the definition "br-latin1-us". That one works. I hope this helps others with the same problem.

And for the developers of Puppy: not all users of the US Internationale keyboard settings are Brazilian! Please change the name of that definition into "US International", as in other Linux distributions.

Greeting, Pjotr.

I think it should be named european since the users are mostly european.
