@user45266 Fwiw I used the unix tr program from cygwin. tr 'a-mn-zA-MN-z' 'n-za-mN-ZA-M'.

Easy, if you remember that 'M' and 'N' are the middle 2 letters.

@user45266 I hadn't seen you around for a while, I was hoping you were alright. Good to have you back!

@Richard Great to see you as well. Always great to get back into the swing of things, especially in this amazing community!
