What is ffxiv mouseover macro?

In Final Fantasy XIV, a mouseover macro is a macro that allows a player to use an ability or skill on a targeted party member without having to select them first from the party list or in the game world. Instead, the player can hover their mouse pointer over the intended target, and execute the macro to use the ability on that target. Mouseover macros can be very useful in group situations where a player needs to quickly target and heal or buff specific party members. They can also be used for offensive abilities as well, allowing a player to quickly target and attack an enemy without needing to tab or click on them first. However, it is important to note that mouseover macros can be less precise than traditional targeting methods, as the player must keep their mouse pointed at the intended target while executing the macro. Additionally, some players may find mouseover macros more difficult to use if their computer system lags or if they experience input lag in the game.
