Is there any way to disable the whole-screen copy when there is no active selection?
When pressing Ctrl-C (or Ctrl-Ins if that's what's defined in settings) with no active selection, the entire screen gets copied. If you then hit Ctrl-V it pastes the entire contents of the screen. This is a big problem because it you accidentally hit Ctrl-C then Ctrl-V when editing, you end up with garbage in your file, and if there was a "fi" on the screen it becomes permanent, requiring restoring from backup.
Example - after the first "12", I intended to hit Ctrl-V to paste in "r/7/9" and instead managed to hit both Ctrl-C and Ctrl-V at the same time, which ended up pasting the contents of the screen and filing some records I had intended to edit that are now in a questionable state. Thankfully this is a tame example and I will be able to correct them without restoring from backup, but it's still frustrating have to do cleanup.
