This question already has an answer here:
I'd like to press, for example, the Menu key and the output be as if I pressed Ctrl+R or another combination of keys. In other words, I'd like to set aliases for combos using the same graphical user interface (System Settings/Keyboard menu) provided by Ubuntu 16.04 to set/change keyboard shortcuts. Thanks in advance!
LE: I do not want to install Autokey, I want a builtin functionality as I already mentioned above. In plus, Ctrl+R does one thing inside a browser window and another thing inside a terminal window. I just want, for example, to press Menu key and Ubuntu to think I pressed Ctrl+R. That's all. I hope I was clear enough. Just a suggestion.
