R ALT-X works for me on a 2014 Acer Aspire E5 Laptop.
I wonder if the root of this issue is that there no longer seems to be a
keyboard standard (as we knew it in DOS); where TSRs were the norm.

I have several TSR programs connected to either Left Shift or Left CTRL and
my favorite TSR (PC-OUTLINE) with a <CTRL /> only works in DOS 3.31 or
below. All I get now is an echo of the key combination with that one. All
of my other TSR  programs are functional except Collins dictionary and I
have a work-around for it with WPShell and WP60.
