Copy and Paste 2-Key Keyboard SAYO OSU Keypad Hotswap One Handed Mechanical Gaming Keyboard Cherry Switch RGB Backlit Mini USB Keypad for macros or Rhythm Games

UPDATE: seller provided a udev.rules file that resolved the Linux issues: https://dl.sayobot.cn/udev.txt - after setting that up, https://sayodevice.com/ works fine on Linux too.I bought this to reprogram the keys to do other things besides copy/paste. I completely failed to do this on two Linux laptops - sayodevice dot com UI loads, lets me select the HID device, and then nothing. I then tried the Linux binary from the zip bundle. If you can get the shared libs installed, it runs, then it opens a web UI (a different one), and that one can't find the device. Tested all of this with the latest Chrome and Edge (doesn't support Firefox)Eventually I tried it on a Mac and the web UI worked (initially that was glitching too, but it was the cable). So, if you have a Mac, you may be OK.The configuration UI is aimed at programmers - you can write a script in what seems like their own macro language. It's fairly easy to set up basic actions like keystrokes and text/password entry and color schemes for the LEDs. Changes take effect immediately but aren't persisted until you press the hard-to-find save button.In the end, "Linux support" was a dud. If I have to reconfigure this thing, I'll need to find a Mac, again.

Recently I’ve been having muscle pain in my arms and I wfh on a computer all day. I had to go off work for a couple months and when I returned I was worried that I wouldn’t be able to get through the days. About 90% of my job is just copy and paste data so this tool has allowed me to work effectively without having to hold my arm up. Highly recommended for anyone in an analyst type position.

Item was as described and shipped quickly. Very handy device.

I love this thing, and use it every day at work. I build lots of Excel spreadsheets for reporting, and having this has saved me so much time when copying/pasting formulas. The buttons provide a great feel and feedback. The lighting is bright enough to be able to see the keypad and the keys themselves. You get 6 buttons (3 sets of 2 each, white with copy/paste, black with copy/paste, and solid black). The build quality and design are fantastic. I love that it's low profile but built tough. And the best part is the value for the money. I have recommended these to co-workers and friends.

I plugged this in for the first time and it did light up for roughly but then it went off and never worked. I never got to use the product. So I will give this the least amount of stars possible.

Just a wee two buttons but I use it for work and it's been a dream.Took me a second to get used to (muscle memory of "Ctrl + C/V") but I use it daily. I find myself wanting one for my home set up, my lap tops, even my phone. Additionally because it's a simple device, I didn't have to get permission from our IT department to use it.I use copy and paste a lot, but the buttons are easily programmed and can be whatever you need it to be i.e. A line of code you use often, repetitive words for CAD, a string of keyboard commands, etc. Plug it in, go to their website to register what you want the buttons to do, and it's ready to use. Also comes with different keys so you don't have to use the ones with "Copy/Paste".Super easy. Super cheap. Super worth it.

I copy and paste probably hundreds of times a day at work. So much so that stretching my hand from CTRL to C and V actually starts to hurt after a while. This button, while silly, is my favorite thing on my desk. There isn’t much to review. It works perfectly and lights up. I took a star off because it is supposed to be programmable through a browser but that doesn’t work at all. So I wasn’t able to change the light pattern or change what the buttons actually do. Not that I’d want to, Infot it for copy and paste. It comes with interchangeable buttons as well. You can change them from black to white. And there is a third set of blank black buttons if you are able to change the function from copy paste to something else. If I got it for something other than copy paste aid be mad but it’s fine. 4 stars. Probably will get another one for home. It’s so stupid but I really do love it.

This Thing Is God Sent!!!!!!
