Whenever someone launches file manager from launcher
/usr/bin/nautilus is executed through
nautilus.desktop. Now, in nautilus, if the user presses ,Ctrl+T, a new tab is opened. For this to happen, some file or commands must be executed. Where are these files or commands stored?
There are no keyboard-specific executables in
usr/bin/. In short what does OS do when some keyboard shortcut is used?
