Searches here and there have me confused.  Believe you can't enter ILS frequencies on the VOR radio panel (pop up and in center console in VC), however, when I try to input them to the CDU as in post #3 in this other thread:

for some reason the keys don't work and nothing changes.  Mark has separately helped me use the CDU to import either an FSX FP  and/or input a simple "direct to" route.  I would now like to be able to simply tune the ILS landing runway frequency when approaching an airport (rather than adding this with all the longer CDU inputs on departure) so that the AP captures the loc and GS.
