 ==== Macros Triggered by the User ====
+Although it is rare to have multiple macros triggered at the same time, the normal behaviour in Keyboard Maestro is that all triggered macros run simultaneously, with actions from each independently triggered macro running at the same time.
-The normal case is that all triggered macros run simultaneously (or synchronously), although you rarely have multiple macros triggered at the same time.
+Most macros are triggered explicitly manually, and typically the user waits for them to complete before they trigger another macro. So macros triggered like this will rarely run at the same time.
-Most macros are triggered explicitly by the user, and the user expects them to complete before he/she triggers another macro. So macros triggered like this will rarely run at the same time.
