Copy & Paste between gets using buttons

[MarcoBoschi]

Hi,
in yoyr opinion is it possible to add in a dialog one or more buttons with these action: copy, paste, undo?
For not-expert user is difficult to click right mouse button to open contextual menu.
I've tried a lot but I note that when I click for instance copy button the get loses the focus and selected text too.

It would be nice to create buttons that do not take the focus


Bye
