[Biococoa-dev] strider and gck format

[Alexander Griekspoor]

Pretty cool actually, I just discovered that with the new  
implementation if you first doubleclick to select a 10 nucleotide  
"word" and then shift click somewhere else it will extend/crop the  
selection also per 10 nucleotides...
Cheers,
Alex

     Claiming that the Macintosh is inferior to Windows
     because most people use Windows, is like saying
     that all other restaurants serve food that is
     inferior to McDonalds
