Pauses execution to let the system process other events.

* The DoEvents function always returns zero.
* DoEvents passes control to the operating system. Control is returned after the operating system has finished processing the events in its queue and all keys in the SendKeys queue have been sent.
* DoEvents is most useful for simple things like allowing a user to cancel a process after it has started, for example a search for a file. For long-running processes, yielding the processor is better accomplished by using a Timer or delegating the task to an ActiveX EXE component.. In the latter case, the task can continue completely independent of your application, and the operating system takes case of multitasking and time slicing.
* Any time you temporarily yield the processor within an event procedure, make sure the procedure is not executed again from a different part of your code before the first call returns; this could cause unpredictable results. In addition, do not use DoEvents if other applications could possibly interact with your procedure in unforeseen ways during the time you have yielded control.
* For the Microsoft documentation refer to

Dim PauseTime As Integer 
Dim Start As Single
Dim Finish As Single
Dim TotalTime As Single

PauseTime = 3
Start = VBA.Timer()
Do While VBA.Timer() < (Start + PauseTime)
Finish = VBA.Timer
TotalTime = Finish - Start
