Hi,
Either I didn't get how to do it or this is a subtle bug:
I'm on Linux, when I copy something from the editing window with the mouse and I paste in the terminal pane inside geany with the central mouse button, the terminal pane doesn't get the focus, pressing enter makes the copied line(s) disappear in the editing window and doesn't issue an enter in the terminal (this is the expected behaviour).
Should I file a ticket?
Thanks.
