In Emacs terminology, the line at the top of a window is "header line",
and the line at the top of an Info node buffer is "node header".

However, in some Info nodes the long node header might not fit on
the header line.  One solution is to truncate the long node name
and display it in the header line partially with an ellipsis, e.g.:

sort invoc...  Next: uniq invocation,  Up: Operating on sorted files

In most GNU programs the next search command is bound to `n' key,
but in Info this key is already occupied by `Info-next' command.
One alternative is to bind it to `N' key, but usually this key is used
to repeat a search backwards.  Then another possibility is to bind it
to `S' key, which was suggested for `Info-search-case-sensitively'.
Since `Info-search-case-sensitively' is quite rarely used command,
its suggested keybinding `S' could be rebound to `Info-search-next'.
