I found xclip.  It wasn't like she'd gone missing and I can't for the life of me work out why I never looked for her.

xclip allows you to take command line output (say an error log) and push it to the X clipboard allowing you to simply past the data onto a webpage (a bug report for instance). I'm rather embarassed to admit that I used to open a file in vim and copy and paste blocks of data, I feel like my repressed Windows gene just made me blind to a better way.

You probably want to read more to discover her other secrets.
