SFML Version 2.3.x fresh pull from Git (<24hours old)
Fedora 22 custom spin (which I'm developing) both i686 and x86_64 builds see the issue Kernel 4.1.5-200
101 Key USB Keyboard, various laptop keyboards.
All QWERTY US Keyboards.
I'll have to figure out how to determine the answer to that first question set. I would presume I do get an event as it is a standard key. usually found to the right of the standard US 101key keyboard Numpad0 key. My apologies for my somewhat amateur approach to this as I'm a systems admin and have not performed any deep coding in nearly 15 years, so I'm more than a scoche rusty. Oddly the use of the other numpad non numeric keys seems to function as expected within the application (EmptyEpsilon/SeriousProton) that I am attempting to crawl down into the code of... +-*/ all work.. but . on the keypad does not. I'm working on tearing into the code and disassembling things from the wrong direction (top down to the detailed breakdown) to trace it. Looking at the SFML Keyboard::Key enum I noticed the absence of that particular key which seems to be the remaining multifunction US layout keypad key.
