If you don't need an assist, then don't bother with FTL Assist in there.

As far as the setting to use FTL or not, leave that at default for all mapped keys.
If you need an FTL assist, then use a Do Mapped Key Action, with the current window as the target.
If you don't need an assist, then don't include the mapped key as part of your action.

The majority of my mapped keys, trigger off of a key push, and send that same key to either all windows, or only specific windows.

Here are a few examples of what I use:

Trigger - Shift F5
Action (one step) - Sends keybind Shift F5 to Target: All Windows

I place my flying mounts on this keybind for all toons.


Trigger - Down Arrow
(Hold Keystroke While Key is Held >> Set to 'On'... this is the option immediately beneath the hotkey).
Action (one step) - Sends Key: Down Arrow to Target: Window - All Without Current

This is for independent slave movement. I use Up Arrow, Down Arrow, Left Arrow and Right Arrow, each constructed just like this one.


Trigger - Shift J
Action (one step), two actions:
- Top Action: Do Mapped Key Action >> New Mapped Key Action.
---- Keymap: General; Mapped Key: FTL Assist Me; Target: Current Window
- Bottom Action: Keystroke Action >> New Keystroke Action
---- Target: All Windows; Keystroke: Shift J

I have targetable single target buffs on this keybind for all teams. Nice for rebuffing a toon who has died or been purged etc. Also useful to buff others not in on my team or in my group.
