Dave, I checked to make sure there are no conflicting keys in MSFS2020.
Ctrl+Shift+T (is available in MSMS)
Ctrl+Shift+\ (is available in MSMS)
Unfortunately I press "0" to contact Clearance and I get my clearance, but then I press Ctrl+Shift+\ to "rogr" the instructions and get nothing...plus Ctrl+Shift+T does nothing again, and I checked the settings again and they seem to be correct from your instructions. I do want to get this resolved for me since Im interested in purchasing the product.
I have added a new log
