We don't know anything besides the laptop being from early 2010s so all we can guess is that it might be Plus, or a mute audio key, or it could just be a "Pause/break" function key, maybe an eject key. Google for a website that does a key function test so when you press that key you can see what it actually is, here is one I found: https://keyboardchecker.com/. Source: 6 months ago

But now when I press the Office Key it's like I'm just pressing End, and then I press the Emoji Key it's like I'm just pressing Space. It worked on https://keyboardchecker.com, but not in-game. I've played around with *, {Blind}, ^!+, etc., but nothing I do gets it to continue allowing me to apply modifiers to End without making the Emoji Key go back to overlapping. Source: 10 months ago

Try using https://keyboardchecker.com/ and see what lights up when you press M. If multiple things are lighting up, you may have an electrical issue with your keyboard. Source: about 1 year ago

That doenst sound like a keyboard issue.What OS? What happens if you use delete key in text editor? Behaves as expected? You can check what key codes the keyboard generates when you press delete: maybe try this site https://keyboardchecker.com/ You could also boot off a live-CD for Ubuntu or something and just test the keyboard in Ubuntu - see how it behaves... Will help you figure out if it's hardware or... Source: about 1 year ago

I investigated the behavior with Keyboard Checker and found that, when I pressed the left Ctrl, and then the Z key, pressing the Z key released the left Ctrl key, which explained the z string. Also, this behavior is unique to that exact physical key. For example, on an American layout, my keyboard would start inputting ys because that's the character mapped to this physical key on that layout (tested). Source: about 1 year ago

In an effort to restore them as much as I could, I used a combination of waifu2x ("Single-Image Super-Resolution for Anime-Style Art using Deep Convolutional Neural Networks"), Clip Studio Paint resize/cleanup tools, and manual cleanup done by hand. Unfortunately, the red text on the title page was a lost cause. If anyone can decipher solid red rectangles please contact me lol. Source: about 1 year ago

Maybe this would help. There's also an app version of it. Source: about 1 year ago

I would recommend putting it through an upscaler beforehand, it seems a bit small. Source: over 1 year ago

Http://waifu2x.udp.jp/index.html found this image upscaler from https://www.reddit.com/r/FireEmblemHeroes/comments/a51f0k/i_turned_yusuke_kozakis_artwork_into_a_high/?st=JPIZKYIB&sh=f12f76fe a while ago, perhaps that would be the closest if IS doesn't release anything. Source: over 1 year ago
