Macros not working and it isn't the quotations

That's more than a small reminder. It's a good heads up. That really sucks since I'm finding it difficult to target specific players/mobs where there are a lot of mobs on the screen. As a DD it isn't all that bad, but as a healer, and I presume tank as well, it is.

As healer, you're usually best off selecting members from the party list (assuming it's party members you want to heal). On controller, you can cycle through the party list with up/down arrow buttons. On keyboard it's done with the first 8 function keys (or you can configure something in the keybinds options if you prefer the up/down cycling like controllers use).

If you need to heal non-party members (like at a large FATE, or when there are NPCs in a duty), that party list selection obviously won't work. Your best bet for that is to set up different target filters. (I only know how to do this for controller, though I'm pretty sure it can be done for keyboard as well. Keyboard might need an extra setup step for assigning keybinds for it, though.) Under the "Filters" tab in the control settings of character configuration, you can specify up to four different sets of target types. (For instance, you might have one that just selects enemies, another that selects players and NPCs, and another that selects everything.) Then the controller's L1 + one of the right-hand face buttons can be used to select among those four targeting filters. For healing (when you can't just use the party list) change your filter to selecting friendly characters only, and then you can cycle through those targets only without the selection falling on mobs as well. Once everyone's healed, and you're ready to DPS, switch your targeting filter to enemies mode, and you can target the mobs.

I personally just click the name of the player I want to heal from my party list to target them.

As said in this thread, healing with macros isn't really as bad for your performance than using macros for damage, and there are many healers who heal with for example mouseover macros. I personally healed the first raid in the game with mouseover macros. But I felt like sometimes macros felt unresponsive or otherwise clunky and not being able to queue my heals annoyed me. But try both and see how you feel about it.
