Maybe it helps to give some context: The discussion started with the 
problem of skipping notes in lyrics (using \addlyrics {} / \lyricsto {}) 
in the documentation. In order to skip multiple notes, the documentation 
currently suggests ugly things like

\repeat unfold 2 { \skip 1 }

that
a) are very cumbersome,
b) contain a mandatory-yet-unused duration argument.

I think b) can be remedied by using "" instead of the skip (I'm not sure 
yet if it's really equivalent), which leads to

\repeat unfold 2 ""

And I think it would be nice to have an even more natural variant for 
that; I think it's reasonable to provide & show/recommend convenient 
solutions for standard tasks (rather than say "you can define your own 
abbreviation here if you know how to do so") - for example,

\*2 ""    or    \x2 ""

which would be my favourite.
