IDA pro asm instructions change

Question

I just want to know how I can change asm instructions in the IDA-view A:

1. How to edit instructions(for instance: jnz to jmp)?
2. How to insert new instruction

Answer 1

Use Edit->patch program->assemble to write in assembly syntax

Use Edit->patch program -> patch bytes to edit bytes in the binary

Finally, use Edit->patch program -> apply patch to input file to apply patches. I'v personally used it in IDA 7.0
