That's great for experts, but difficult for everyone else because the same connector can expose wildly different capabilities depending on the implementation.

#12I use an Apple Silicon Mac and often use programmable keyboards like the Royal Kludge RK61 via USB C. when I press keys such as A, S, D, F, W, or nearby keys in quick succession, the keyboard stops responding completely until I unplug and reconnect it. I've even replaced the USB C cable with a new store bought cable, but the issue still persists.

Usb isn't the issue, you bought an extremely budget mechanical keyboard.

#15Then in the section where it tells you how to do that, it fails to properly explain how to connect a load switch (10 cent component at 100 units) to get around the 10uF limit. The vast majority of applications will require less than 15 W and a good chunk of them can't get away with 10uF between VBUS and GND so a schematic how to do it in the lowest cost way would have helped here.
Edit: After reading until the very end I got the impression that this is just an ad for Texas Instruments PD controllers.

Check if your keyboard has a way to enable n-key rollover (NKRO) https://en.wikipedia.org/wiki/Key_rollover
I use usevia, all i had to do was find a keyboard definition file for my keyboard which claude found in 2 minutes!

my keyboard is actually r65 by royal kludge i got that wrong!
I was gifted this keyboard and i just love its feel.

#19Guides like this explain why there are so many broken USB-C devices. The guide mentions that you do not need a PD chip for 5Vs, but then tells you that USB C is a cold connector meaning 0V is on VBUS when nothing is connected and jumps straight into the complexities of the PD protocol running over the CC pins instead of explaining how to get the 5V without the PD chip first. Then in the section where it tells you how…

Might be for cache busting.
could be, but for pdf documents I would assume that they are not changing this much
