The Bug that isn't a Bug
Ok so, about a year ago (maybe 8-10 months? I don't know, whenever the last win 10 update was) I started having this problem: > None of the keybindings work. QWER DF B P O S ... they're all broken. none of them work not even 1234567 keys work. Sometimes Alt and certain keys will work, but mostly it doesn't work. Cant use any skill shots, and most other things without the mouse. The mouse is the only thing that works, now.
I reported this to riot, they tried their best back when I made this post and requested help from riot support. After months of me dealing with this random issue, I have noticed the cause BY CHANCE: I have windows 10, and it's pretty and shiny, and it's a LOT better than windows 8, but still has it's pitfalls. Least of which is the fact that STICKY KEYS turns itself back on after every start-up. ↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓ I press the Shift key, and then change my mind about making "r" into "R" but it still turns into "R" because of sticky keys. I hate sticky keys. I wasn't typing often enough last year to notice the issue of sticky keys, and they seem completely unrelated, so I never made the connection until now. ↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑ I turned off sticky keys around January, when the latest semester of college began, and last month though this month, I noticed that there was no longer a problem with Key Bindings, or any of this mess. It was a huge relief. And then windows 10 updated, and I had to restart my pc. (I rarely turn off my pc) After restarting, the sticky keys turned itself on again, and the in-game issue of keybindings came back. Again, it took me a few days of this to even think of this being related. I never got rid of my old keyboard, and it turns out that it was never the problem. (I might buy a new one now, though). But, sure enough, after turning off the sticky keys.... everything works normal. Problem solved. ... at least until the next win 10 update.
TL;DR: STICKY KEYS fucks with the client. It wasnt my keyboard OR riot's client. It was windows fuckin 10 Sticky Keys.
