Trying to find a way of doing this, though now starting to think it might be not possible yet.
I need a way to add a custom menu item to the context menu, which appears when you "right click" any link on the page.

So for example, i'd like to add a menu "Send to..." right below "open link in new tab" menu option.
I already have such plugin written for Firefox, and need to port it to Chrome, but I just cannot find anywhere how to work with context menu...

Hi Afin. We'd all love that! The menus aren't modifiable - not much is at all actually. Though you can put a drop-down menu on a button, as detailed here.

The facebook enhancer (or what is was named, I forgot) does this somehow ...

Trying to revisit the problem again. Anyone has any thoughts on this problem? Can it be done after all?

This will be possible when this bug is fixed:

Add a menus extension API:

Yeah man, What the heck.
Not to drop names here and compare browsers, but Firefox has a beautiful and useful right click menu that doesn't even need to be personally customized, it just automatically adds appropriate and usable tabs from the add-ons you've installed.
The biggest and most useful one is 'AddThis'!!! In Firefox, I just right click on any picture, video, page or anything and add it to wherever i want.
Another useful right click button is 'LaterThis'
