Another recent thread made me fool around a bit with KEYBD /C. In a new TCC session, "KEYBD /C" will toggle CapsLock on/off (but not off/on) exactly once; thereafter it will do nothing. Exiting TCC after "KEYBD /C" once leaves CapsLock on ... in another new TCC, "KEYBD /C" does nothing, "KEYBD /C0" will turn CapsLock off and another "KEYBD /C0" will turn it back on and further "KEYBD /C0"s do nothing. Also, in a new TCC "/c1, /c1" (abbreviating now) will turn it on/off (and then become useless, like /C alone) ... then /C0 will turn it on (and become useless, like /C1) but a /C will turn it off. I can't make sense of it. Any of the three (/C, /C0, /C1) **may** toggle the state and none of them work more than two times in a row.
