Im using CentOS 6.5 workstation, pretty standard config, with normal dell keyboard, EN/US lang and keyboard layout. I have the following in the .Xmodmap
keycode 66 = Control_L clear Lock add Control = Control_L keycode 117 = Caps_Lock add Lock = Caps_Lock
Which maps Caps to Ctrl as I desire. A few times a day I somehow trigger caps lock, sometimes in the browser, sometimes from the shell, there seems no pattern to it yet there must be. I can't figure out what Im actually pressing after the event, but more to question, what combination would enable one to toggle caps lock when the above config is active?
