'   SetHotkey 1, "Ctrl,112", "Add"        '按 Ctrl+F1 激活指定程序
'   SetHotkey 2, 113, "Add"               '按 F2 激活指定程序
'   SetHotkey 3, "Ctrl+Alt,113", "Add"    '按 Ctrl+Alt+F2 激活指定程序
'注释：注：关于激活热键后的操作，由自定义函数 SetHotkey 的 KeyId 传送的值来判断
'注销 3 个热键：
'   SetHotkey 1, "", "Del"              '退出程序是一定要用上的，不然会导至程序死掉
'   SetHotkey 2, "", "Del"
'   SetHotkey 3, "", "Del"
'请大家新建一个模块（.bas）文件，自定义 SetHotkey函数及其他，这样在以后的任何程序中只要调用此模块就可以了。
'注释: 本模块是有关热键操作的
