The Keyran program allows you to create a unique macro for PvP in the Minecraft game. For example, for version 1.8.9, we can create a macro that will increase the strike range. To do this, you can use the W Tap key combination, which is one of the types of combos. In this combo, the character goes forward and stops for a second so that the opponent can't reach you. 

By creating such a macro, you will get a significant advantage in PvP battles. The W Tap key combination can be configured in the Keyran program to activate with a single button on your keyboard. This will allow you to easily use this technique during combat situations, providing you with additional invulnerable time.

Thus, by creating a unique macro using Keyran, you can significantly improve your skills in PvP battles in Minecraft 1.8.9 and overcome your opponents with ease.
