Based on an analogy that I saw in another thread...
If you were to bind forward to the 3 and the strafe left key to 4, and then glue a penny across the two keys.
The one physical press by you, presses two keys at once in the game.
It's the same idea as the FTL set ups.
We are pressing 1, but depending what toon we are on, the game will also be receiving a combination of:
(Left or Right) Alt keys and (Left or Right) Shift keys and (Left or Right) Control keys.
Or consider a spell which we hotkey to say Shift F7.
You are pressing the Shift key and the F7 key at once.
But are in no danger of being banned for doing so.
With a castsequence, we can spam the key very quickly.
Or we can wait 17 seconds between each press of the key.
Which is the same options we have with a Keymap with more then one Step.
It doesn't matter how either is constructed, as they perform according to predetermined steps and make no intelligent decisions based on whatever. It's just this on press 1, this on press 2 etc.
In all of these cases, one thing happens when we push one key or combination of keys.
And then we need to push another key or combination of keys for something else to happen.
We might be pushing 1, on our keyboard and having the software push 2 within warcraft.
But that doesn't change that we are getting one action from one keystroke.
With my Interact / Stop Follow key.
While my software can place the hotkey for each action on the same key.
It is two keystrokes for two actions.
The delay between the actions is determined by my click speed.
Exactly the same as if I used two hotkeys or one key with two steps.
And exactly the same as if I were to do it within Warcraft by pressing Interact -choosing how long I wait- and then pressing down arrrow.
