Summary MESS-specific 07859: jupace: Natural keyboard playing up
Description When using the natural keyboard, the shift keys do strange things.
Steps To Reproduce >mame64 jupace -natural

Hold left shift, hit a key - nothing happens.
Hold left shift, hold a key for a while, let keys go - when Shift is released, suddenly a whole bunch of letters appear
Hold right shift, hit a key - nothing happens.
Hold right shift, hold a key for a while - does the same as left shift. Right shift is supposed to produce symbols, but that is now impossible.
Additional Information Sometimes if you hit a bunch of keys with shift you might get a random capital letter appear.

'mbee' also has a natural key problem where lower-case will not appear, yet uppercase (with the shift key) works fine.

Like the jupace, this was all working fairly well a few months back.

Are you sure it's not just releasing the key before the emulated machine registers it? The natural keyboard manager is posting input events correctly.

I did turn on logging in natkeyboard.cpp and the uppercase registered correctly, but symbols shift was being interpreted as normal shift (which is incorrect). Nevertheless, the uppercase was not making its way to the actual machine, but I couldn't figure out the path that takes.

Once I finally found my natural keyboard spreadsheet, I found that jupace was problematic even then.
So, let's just close this, even though I think something weird is going on.

I think the issue is just that the one-size-fits-all delay in the natural keyboard manager doesn’t work well with this machine.
