how to paste selected text / keyboard shortcut

[mrr <mireero@free.fr>]

Hi everybody.

Ok, my question is in the title but I think I should be more precise so:

I often use the mouse to select some text and then I can paste it using 
the central wheel button of the mouse (that can be simulated by clicking 
both buttons if you don't have the wheel button but I'm getting out of 
subject...).

Is there any way I could paste the selected text with a keyboard shortcut ?

Maybe this isn't possible with only one shortcut as pasting may depends 
on the application _taking_ the paste (I mean that pasting some text in 
thunderbird or in a shell might involve a different logic but it sure 
works with the central button the same way so??).

It's not that important but I'm so lazy and taking twice in a row the 
mouse uses my right hand!

Cheers,
