How do you interpret a keyboard layout?

I have activated the keyboard for Indian scripts as shown here. Upon checking the keyboard layout, I find 4 symbols mapped to one key:

here

I am able to input the characters

  • denoted in the bottom left of the key by pressing the key normally
  • denoted in the top left of the key by pressing the key with shift

I want to access the symbols on the right side of the mapping. How can that be done?


You can input the symbols

  • on the bottom right by using right alt
  • on the top right by using right alt along with shift.
