ਪੰਜਾਬੀ-ਅੰਗ੍ਰੇਜ਼ੀ ਕੀ ਬੌਰਡ
Punjabi-English keyboard

This page is for illustration purposes and is derived from one that I have on my desktop.
Note: that the tippi and bindi are the other way around on a Linux keyboard mapping.
Also, if you were wondering where ੳ is on the keyboard, the letter never appears without some sort of modifier - you can see it as ਉ, ਊ and ਓ in general use.
The same also applies to ੲ which only appears as ਇ, ਈ and ਏ
