Map Caps_Lock to Ctrl in linux

In linux, Caps_Lock is mapped to Ctrl. I used debian7, which used to be gnome desktop. The system has settings for changing the keyboard layout. Before gnome collapsed once, it was replaced with openbox, and it can be used very well with a little configuration. However, the keyboard layout cannot be modified in the system... in linux, Caps_Lock is mapped to Ctrl. I used debian 7, which was a gnome desktop. The system has settings for changing the keyboard layout. Before gnome collapsed once, it was replaced with openbox, and it can be used very well with a little configuration. But I didn't find the keyboard layout changed in the system, so I searched for related blogs on the Internet to exchange ctrl and caps lock. http://www.2cto.com/os/201306/222522.html Inside. the content of the xmodmap file is like this [html] remove Lock = Caps_Lock remove Control = Control_L keysym Control_L = Caps_Lock keysym Caps_Lock = Control_L add Lock = Caps_Lock add Control = Control_L move the left ctrl, caps lock switching, I found that the usage of caps lock is very low, and it is easy to accidentally press to the left ctrl after switching, resulting in incorrect case switching. So I tried to change [html] remove Lock = Caps_Lock remove Control = Control_R keysym Control_R = Caps_Lock keysym Caps_Lock = Control_R add Lock = Caps_Lock add Control = Control_R, caps lock and ctrl are both functions of ctrl. Run [plain] xmodmap ~ /. Xmodmap 2> run xmodmap in/dev/null. we can see that there is no change before the change.
