How can I set Rgui.exe for backward search

Question

If you use Rterm.exe, a nice feature is that:

CTRL+R : backward search meaning CTRL+R+lib will show last command starting with lib like library(Rcpp)

Rgui.exe seems to lack this feature. Can I add it somehow ?? I use Windows 7, and changing is not an option.

This is what Brian Ripley had to say about this request (albeit 6 years ago):

good, so I was right to use Rterm.exe see #14237967 but as you know I have a problem with it. About contributing, I am afraid this is well above my current skills else I would have commited the patch a long time ago... – Preach

I found that there are extensions to readline and put details in an edit to my answer on that other page – Inharmonic
