Resolves: tdf#123825 reassign mnemonic for Diacritic-sensitive

since....

commit beeef93480fae65840646e4e36aa888efe92579a
Date:   Tue Mar 8 19:54:57 2016 +0530

the "Search For" label is invisible

so the _S can be safely removed from that and assigned to Diacritic-sensitive
instead, removing the dup _r assignment leaving only Replace using _r
