Help! Player/object markers screw-up

[Crashbangwallop]

Seems I've accidentally hit a key combination that's changed 'pilot name' to plain 'aircraft type' – makes finding myself from the opposing aircraft POV in dogfight tracks impossible. Just optimistically hitting 'I' isn't doing it, and it's mildly annoying

 

There's bound to be a toggle/cycle icons button somewhere – I remember one from old IL2 - but can't find it Key Mapping and am loathe to randomly scrabble around on the keyboard for fear of screwing anything else up

 

Anyone able provide the simple answer?

Well, that seems to have finally sorted itself out turn on/turn off style. Back to normal

Which is nice.

 

But I wish I knew what I'd done in the first place to make that happen
