How do you set up a new hotkey on keyman keyboard?

I need help on how to set up a hotkey for the √ root symbol on the Transliteration for Devanagari keyman keyboard.
Thank you.

Welcome to the community @Judy,

To setup a hotkey for keyboards, read How To - Set Hotkeys for Keyman Desktop, Keyman Keyboards and Windows Languages.

Do you also want to add the √ root symbol into Hindi Devanagari Phonetic (ITRANS) keyboard? To do so, you need to edit the source file using Keyman Developer.

Documentation on Keyman Developer:

Please ask if you have more questions.

Thank you!
