Command key is not working for selecting multiple files or folders
I dont know why but the command key is not working for selecting multiple files or folders only. Using Command + z, s, c, v, etc were working without any issues. Any idea why? Btw, Im using Corsair K95.
Also, when I command+click, it also not working.
