Copy & paste in a terminal without SHIFT

You can change your settings in Gnome Terminal keyboard settings to make

  • Ctrl+C = Copy
  • Ctrl+V = Paste

Menu > Edit > Keyboard Shortcuts... Gnome Keyboard Shortcuts Settings

Then you can still press Shift to do whatever that key combination would usually do in a terminal, e.g.

  • Ctrl+Shift+C = Interrupt
  • Ctrl+Shift+V = Literal Next Character

Alternatively, you could get into the habit of using

  • Ctrl+Ins = Copy
  • Shift+Del = Cut
  • Shift+Ins = Paste

in all applications, to avoid ever accidentally pressing Ctrl+C in your terminal and having it abort the program instead of copying some text. Those shortcuts date back to the IBM Common User Access standards. Some people might remember them from DOS EDIT.
