How to enter "ज्ञ" in ubuntu 14.04 hindi keyboard

Question

I'm having trouble typing "ज्ञ" (gya) in Hindi.

When I updated ubuntu from 13.10 to 14.04, I noticed that the outdated Hindi keyboard was missing, instead, in the text input settings, I saw three new Hindi input sources:

Hindi(Bolnagri) Hindi(Wx) Hindi(KaGaPa phonetic) 

Once, when I was typing in LibreOffice Writer in Hindi, I had to type “ज्ञान”, but I could not find the letter “ज्ञ”. I searched for key layouts and character maps of all three input sources, but could not find them ... (This problem remains with text editors!)

Please help me and tell me where it is on the keyboard, if you think you know the answer! (it has been a week since I thought: "How can they make such a big mistake, how to forget" ज्ञ "in Hindi !!")

(NOTE: the “ज्ञान” above was inserted after searching “gyan hindi” on google !!: D)

EDIT: Solution:

  ज्ञ = ज + ् + ञ 

There is no specific key for this!

Answer 1

He uses Sanskrit rules such as

  ज्ञ = ज + ् + ञ 

The issue is now resolved !!!!
