I have previously used the Putty terminal in Windows. It does not have mouse scrolling activated within a vim screen, but DOES allow me to scroll "above" the vim window to see previous shell commands/output.
Now I am using gnome terminal. It's behavior is the opposite. It allows mouse scrolling within the vim window, but does not allow me to scroll "above" to see previous shell output. Is there any way to allow me to scroll "up" to see shell output while I have vim open?
