right mouse click in textview

[deloptes <deloptes yahoo com>]

Hi,

I would like to ask you to point me where I may look for understanding how I
can extend the menu that pops up on right mouse click in the textview.

I've tried to google, but it didn't help much as I don't know in which
direction to search... and I'm also not sure I've seen an example on this.

thanks in advance

regards
