Using LINDA Tracer with this absolutely sensational PMDG NGX, I have found a number of LVars of the following format :ngx_switch_nnn_a I am especially interested in the ones that are triggered by mousing the CDU keys. After some patient trial and error I have found that these are in the nnn range 534 to 602. E.g. ngx_switch_546_a changes to 100 and then back to 0 when I click the INIT REF page button, ngx_switch_547_a changes to 100 and then back to 0 when I click the RTE button, etc. I was hoping to use at least the LVars for the page shortcut buttons via FSUIPC, as unlike the line select and alphanumeric keys these do not seem to respond to any of the Tab+... keyboard commands (unless I overlooked something). I have a nice CDU replica (which produces programmable key commands, nothing more fancy than that) and would like to be able to use all of it. My question is : can these LVars indeed be used to operate the CDU page shortcut buttons ? If not, then there's no point me continuing. If yes, then I'm doing something wrong and may need to ask the FSUIPC experts for some guidance. Thanks very much for any response.

Guess my question can only be answered by one of the developers but if so, can the appropriate one PLEASE reply ? All I need to know, is yes you can do this or no you can't. Surely that's not asking too much ?
