action keys

[Wolfgang Engelmann]

How do I initiate in LyX to show the keys for certain actions
Example: alt e and n shows lyx notes / commentary / grayed note
but I have to go to one of them to e.g. select notes
In an earlier version (or better an earlier setup - and I don't know 
where to do that) the keys were shown by an underlined character, e.g. 
n(underlined)ote resulted in note, if n was used. I checked the various 
help files, but did not find a hint (perhaps, because I don't know the 
term for finding it.
