Macro Confusion! What am I not getting?

Havent played wow since WOTLK so i very very rusty. That being said i dont understand macros. I used macros ALOT in Rift but WoW seems to have different syntax/wording…

Thanks for any help

Well 3 ways of going

Macro toolkit but you can use leading zeros any more
Swap bar
Gnome sequencer is the other way ( you get the dowload from wowinterface called Gnomesequencer)

lots of info on forums

i appreciate it! im currently using macro toolkit but it confuses me…
