From the Wiki this makes sense but it might be helpful to post an example and a counterexample of what is acceptable. I was shocked when I learned this trick in the attached pictures that you could use the same key you are using for a macro to keep triggering a macro. Such a useful and helpful trick that thankfully doesn't seem to cause any conflicts that makes navigating a breeze.
Do Not Use for the Keystroke of an Active Hot Key Trigger
You should not use this action to simulate a keystroke that is the same as an active Hot Key Trigger. Typing a keystroke that is the hot key trigger for an active macro has unpredictable behaviour, it may type the keystroke or trigger the macro, and which will vary depending on unpredictable factors including the load on the Mac, the version of OS X or Keyboard Maestro and other factors.
Instead use the Trigger Macros by Hot Key action if triggering the macro is desired, or alternatively, find another way to cause the desired action (eg use the Select or Show a Menu Item action to select a menu instead of simulating a menu command key).
