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: 7 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: 11 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

EDIT: Also if there is a tool where I can search/filter mice by my criteria I'd be interested in that as well. Something like gsmarena.com for computer mice. If it's out there I would love to know because I couldn't find a better way of looking for a mouse that met these requirements than looking through tons of Amazon listings or posting here 😅.

Gsmarena.com shows that international versions have a physical sim in addition to esim. Why the differences? Only Apple knows. Source: 12 months ago

In general, the cell bands used in the US are not supported by many Xiaomi and Redmi phones (not sure if any of them have good coverage of US bands). Check on gsmarena.com for the band coverage and then check your carrier's website for what bands they have service on. If there isn't a good overlap, your phone will not be very useful for making cellular calls or using cellular data. Source: about 1 year ago

I went to Nokia.com and gsmarena.com for specs on this phone. Source: about 1 year ago
