Insert a dead key after backspacing in keyman keyboard rule

How I can insert a dead key after backspacing in keyman keyboard rule ? I want to replace last key stroke with a deadkey. Is Unicode Character ‘BACKSPACE’ (U+0008) support available for keyman ?

I’m not sure I fully understand the question, but [K_BKSP] can be used to reference the backspace key. For example:

‘a’ + [K_BKSP] > dk(backspace)

would delete an ‘a’ character and replace it with a deadkey called “backspace”.

If this is not enough information to allow you to proceed, please ask a followup question.

Reference: https://help.keyman.com/developer/language/guide/ then follow the “Virtual keys and virtual character keys” link to get a list of keys including K_BKSP.

Thank You @drowe . I applied this rule to my code.
