Left-down-clicking in xterms starts the selection of something to be copy-pasted.
Double-left clicking selects a word.
Triple-left clicking selects a line.
All this works under unity in 11.04. However, there is no way to copy-paste that selection to another place: The right-click menu shows paste disabled, and middle-clicking to copy-paste does not work.
So how can I copy a selection from an xterm into another place? I am happy with any method to perform this.
(I am using the default-installation no special configuration so far)
Edit: Same problem with xedit
