Thank you everyone for your replies. Things just get stranger and stranger---see below. I should probably mention at this point that my real goal is not to swap control and caps lock (I want to understand how to do that since it is a common and seemingly simple example). My real goal is: 1. Make the left and right "Alt" keys send control. 2. Make the left "Control" key send alt. 3. Make the right "Control" key send AltGr. 4. Make the "CapsLock" key send compose. 5. Have no key send caps lock. 6. Maybe do somthing with the "Win logo" and "Menu logo" keys too, but this is a low priority since my usual keyboard has neither or these keys. So, back to swapping control and caps lock. Before I modify anything, xmodmap reveals the following: xmodmap: up to 4 keys per modifier, (keycodes in parentheses): shift Shift_L (0xa), Shift_R (0xb) lock control Control_L (0x8), Control_R (0x9) mod1 Meta_L (0xc), Meta_R (0xd), Alt_L (0xe), Alt_R (0xf) mod2 mod3 mod4 mod5 Note that no keys are assigned to lock! Shouldn't this mean that there is no caps lock? But the "Caps lock" key does in fact turn on caps lock. According to xev, "Caps Lock" sends Caps_Lock, and "Control" sends Control_L. Now I run the following xmodmap commands: ! ! Swap Caps_Lock and Control_L ! 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 with the result that "Caps Lock" is still caps lock and does not send control. (It still sends Caps_Lock according to xev.) What is really strange is that "Control" now works like a shift key! Meaning, that if I hold down "Control" and press letter keys, I get capital letters. But number keys are unaffected. So it is really like a caps lock that does not lock (arguable more useful than regular caps lock, but still bizarre.) According to xev, "Control" sends Caps_Lock also. Xmodmap reports: xmodmap: up to 4 keys per modifier, (keycodes in parentheses): shift Shift_L (0xa), Shift_R (0xb) lock Caps_Lock (0x8) control Control_L (0x59), Control_R (0x9) mod1 Meta_L (0xc), Meta_R (0xd), Alt_L (0xe), Alt_R (0xf) mod2 mod3 mod4 mod5 I will keep experimenting. -- Henry House The unintelligible text that may follow is a digital signature.
