Dear All,I'd like to create new audio panel C++ gauge, but unexpected trouble has occur. Namely, I found some key toggles dealing with AFD, NAV, and DME triggering look unoperating (for example, KEY_NAV1_SOUND_SET or KEY_NAV1_SOUND_TOGGLE, and corresponding toggles for AFD, DME, NAV1, and NAV2). As to toggles dealing with COM1, COM2, Both COMs and MKR, all work fine.Could you help me to find the reason of such trouble and the way how to avoid it?Thank you in advanceSincerely

Try KEY_RADIO_VOR1_IDENT_TOGGLE and related.Arne Bartels

Dear Arne,Thank you for your reply. All looks working.It is rather interesting what for another set of the toggles (KEY_NAV1_SOUND_TOGGLE, for example) were introduced...Thank you again
