takemetm / keyboard / - The combination w + a + space doesn't work

Hello today I bought a cheap Take me Standard Keyboard Knock keyboard.
Everything is fine and it works, but I have a problem with one combination. When I hit + a in-game and hit spaces, that space button just doesn't react like I didn't press it at all. The strange thing is that the combination w + d and when the spaces are pressed works fine. I tested simply changing the button in the game, but it's very hard to get used to. I would like to know if I could somehow fix it so that this combination of w + a and space would work. I would like to add that this is the same problem as this topic "https://www.elektroda.pl/rtvforum/topic2403609.html". Could someone describe how to check this keyboard shortcut? Or are there any other explanations? Because it's a key combination for me.

I also wanted to add that the previous keyboards worked with this combination and I had no problems.

Replace the keyboard with another one and check if it's ok.

Yes, on another keyboard it's ok. But the old keyboard is no longer usable. I just don't understand why it's only on this combination. I am familiar with all other possible combinations and only this does not work?


Just checked something. I rebounded the keys (i.e. I set the '' a '' key to 'capslock' in the game it is '' moveleft '' or walk left) and it doesn't work either. I checked in a few games whether new or old, the problem is the same.

Because the keyboard is "cheap", the manufacturer had to save something. Buy a normal branded keyboard, you will not have such problems.

Different keyboards have a different internal matrix connection layout. Most keyboards have 3 keys that will not work simultaneously (e.g. more than 2 arrows). The phenomenon is called ghosting.
