SUMMARYWord does not have a built-in method of delaying execution of a macro, but workarounds can be used to achieve this effect.

http://www.microsoft.com/support/supportnet/refguide/default.aspYou can use one of the following methods to delay execution of a macro using Visual Basic for Applications.
Method 1: Use an Empty For...Next LoopA disadvantage to this method is that there is no direct way to determine the exact amount of time the program will take to execute the loop. The amount of time will be dependent on the speed of the user's computer. The following code will execute a loop that does nothing but take up some time.
For iCount = 1 to 1000 Next iCount Method 2: Use an API Call to Suspend Word's ExecutionUse an API call to suspend Word's execution for a fixed amount of time. The Kernel32 contains a function that will pause an application's execution for a specified amount of time, specified in milliseconds. To use the function, it must first be declared in the General Declarations section of the module in which it will be used:
Declare Sub Sleep Lib "kernel32" Alias "Sleep" _ (ByVal dwMilliseconds As Long)Use the following syntax to call the Sleep function:
Sleep (1000) '1 second delay Method 3: Use the OnTime MethodUse the OnTime method to set an amount of time to pause. The OnTime method uses the following syntax:
expression.OnTime(When, Name, Tolerance)Because the Name argument requires the name of a macro to run, you must create two macros. The first macro to contain the OnTime Method call and other commands relevant to your macro. The second macro to run when the alloted time has passed. The second macro can be a 'dummy' macro that does nothing. This example runs the macro named "DummyMacro" 15 seconds from the time the example is run.
Sub MyMainMacro() ' Pause for 15 seconds. Application.OnTime When:=Now + TimeValue("00:00:15"), _ Name:="DummyMacro" End Sub Public Sub DummyMacro() ' This macro does nothing. End SubFor more information about the OnTime Method, click the Office Assistant while in the Visual Basic Editor, type "OnTime Method," click Search, and then click to view "OnTime Method."
