In Windows 10 when I press the Caps Lock key, I can type numbers and other special characters. Now, in Ubuntu 18.04, I have to keep pressing the shift button to do that. Since I switched from Windows 10 to Ubuntu 18.04, this was my biggest problem.
Also how can I remap my own custom keyboard layout? I searched a lot about this, but I can't find any comprehensible updated tutorial to do this.
