source insight的EM文件 可以扩展SI的宏功能

/* 
	This is an example macro that can be used to create a 
	secondary key mapping which maps keys after an initial
	key press.

	For example, the user presses Ctrl+K, followed by "d" 
	to run the "Cut Line" command.
	
	This example assumed Ctrl+K, but you can use whatever key
	combination you want.
	
	Instructions:

	1. Add this macro to a .EM file and add it to 
	   your project.
	
	2. Use the Key Assignments command to map this macro 
	   to Ctrl+K.  The macro name "CtrlK" will show up in the list
	   of commands.

	3. Now you can type Ctrl+K, followed by another key
	   to invoke either "Cut Line" or "Paste Line".  These
	   two commands were picked by random.  You could add
	   what ever key combinations and commands you want.

macro CtrlK()
{
	// Wait for the next key press and return the key code.
	key = GetKey()
	
	// Map the key code into a simple character.
	//
	// If you only need a simple character, you can 
	// call GetChar() instead of GetKey + CharFromKey
	ch = CharFromKey(key)

	ch = ToUpper(ch)
	
	if (ch == "D")
		{
		// Ctrl+K, followed by Ctrl+D
		if (IsCtrlKeyDown(key))
			// run the "Paste Line" command
			Paste_Line
		
		// Ctrl+K, followed by "D"
		else
			// run the "Cut Line" command
			Cut_Line
		
		
		// Note: you can also use IsAltKeyDown and
		// IsFuncKey to further discriminate keys.
