Number is the toggle number. Hotkey is the keyword and trigger that define the hotkey.
Here's how this command is used. Suppose you've defined F1 as a hotkey with three toggles.
<Hotkey F1> <Toggle> <Text First thing!> <Toggle> <Text Second thing!> <Toggle> <Text Third thing!>
If you want to set that hotkey to its third toggle so it prints "Third thing!" you could make another hotkey like this.
<Hotkey F2> <SetToggle 3 Hotkey F1>
You can only set the toggle of one hotkey at a time. For example, the following won't work because it tries to set multiple hotkeys:
<SetToggle 3 Hotkey A-Z> // DOOESN'T WORK
