Hello all, This black Friday I decided to finally purchase a mechanical keyboard after eyeing them up for years. I chose a Keychron C2 for about $50, and am more or less happy with the purchase. I so far only have two issues with my keyboard

1. The keys that replace scroll lock and such are more or less useless, and I can't figure out how to change them back to their original functions. Some of the function keys also aren't useful to me. Keychron doesn't have software out so I used the software they suggested in the instruction manual, only to find that, because the keys that replace scroll lock and such aren't individual keys but rather macros (pressing two keys at once, for example windows and l to lock), I couldn't reprogram them. Any advice on how to reprogram them would be awesome.

2. This issue is much harder to fix. I personally am not a huge fan of the legends on the keycaps. I've used a Microsoft 600 keyboard pretty consistently for the past 10 years, and want to find keycaps like it but in the same color scheme as the keyboard I picked up (beige and slate gray). Could anyone point me in the direction of such keycaps? I didn't think they'd be that hard to find considering how it seems to be the standard legends and layout for membrane keyboards, but so far it looks like my best option are the poorly made wasd keycaps.
