Options:

Numpad 1: Unlimited Health

Numpad 2: Easy Kills

Numpad 3: Unlimited Ultimate Charge

Numpad 4: Gold Multiplier

Notes:

Numpad 1: Unlimited Health - you must take a little damage first, then toggle this on and your health remains full.

Numpad 2: Easy Kills - cause some damage to enemies at least once, then toggle this on and most enemies are easy to kill.

Numpad 3: Unlimited Ultimate Charge - you must use a charge at least once, and then toggle this on and if you have any charges left, when you use the charge again it won't decrease.

Numpad 4: Gold Multiplier - toggle this on and then pick up gold.  The option is only on for a few seconds, so it's best to use this when there is a lot of gold to pick up in an area.  This option is only on for a short time to prevent the trainer from writing to things it shouldnt.

Temporarily Disable Hotkeys:

To temporarily disable the Hotkeys, press CTRL-H after trainer is activated.  You can use CTRL-H to re-activate the Hotkeys as well.

Creating Custom Hotkeys:

You can click on the actual option in the Trainer application itself to modify the Hotkey or the value used for that option.  The trainer will save your hotkeys for you.  To delete your Custom Hotkeys for this trainer, press the Debug Tab and then press CTRL-K and the keys will be deleted.
