It sounds like you're trying to remap Escape to Power? That unfortunately not the intended functionality of this app.

Does not remap other keys to Power

PowerKey remaps your Power key to output one of the key replacements below.

This app does not remap other keys to function as a Power key.

PowerKey cannot be used to remap any keys other than the Power key.
