How to activate other Microsoft application using VBA

Below code invokes or activates Word application.

Application.ActivateMicrosoftApp (xlMicrosoftWord)

Similarly, replace xlMicrosoftWord to xlMicrosoftMail to activate Outlook. So one can create keyboard shortcut to frequently used application and activate those applications without any manual effort.

However, to invoke other application not listed or supported by above method use Shell command. For example to start notepad application, use the code: Shell "NotePad.exe"
