#5 Physical modifier keys not changing on-screen layout

[zero0]

Hi, and thank you so much for this invaluable tool. Florence is the best online keyboard I've tried so far. I use it on a constant basis as a visual feedback and guiding help when switching keyboard layouts.

However, I'm experiencing an issue with modifier keys (Shift and AltGr). Even though they work fine on my hardware keyboard, they don't change the on-screen layout, which makes finding unusual key combinations difficult. Caps Lock does work as expected, though.

Could someone please help me to fix that?
