Re: Passing current line number to shell command

Crikey. The formatting on Google Groups is making my eyes bleed.

Anybody got any idea of how to integrate vim with gmail other than
cutting and pasting?

I'm using Firefox(esr) on FreeBSD and have "It's all text" add-on
installed but can't find any info on how to configure it.

TIA.


Regards,
