~ 需要Total Commander 的usercmd.ini文件中定义好用户命令，比如em_openDefaultTab

~ [em_openDefaultTab]

~ button=

~ cmd=OPENTABS %COMMANDER_PATH%\tab\!!!.tab

1. 1:: ;TEST

 SendTCUserCommand("em_openDefaultTab")

Return SendTCUserCommand(Command) ; string

 {
   If  Command <>
     {
       VarSetCapacity(CopyDataStruct, 3*A_PtrSize, 0)  ; Set up the structure's memory area.
       dwData := Asc("E") + 256 * Asc("M")
       NumPut(dwData,  CopyDataStruct, 0)
       cbData := (StrLen(Command) + 1) * (A_IsUnicode ? 2 : 1)  ;SizeInBytes
       NumPut(cbData, CopyDataStruct, A_PtrSize)  ; OS requires that this be done.
       NumPut(&Command, CopyDataStruct, 2*A_PtrSize)  ; Set lpData to point to the string itself.
       SendMessage, 0x4a, 0, &CopyDataStruct,, ahk_class TTOTAL_CMD ; 0x4a is WM_COPYDATA. Must use Send not Post.
     }
