Alright so unlike crafting in other games where you just click to craft and it does it automatically you have actions tailored to crafting items when on a crafting job and learn new ones when you level up just like any other job.

“Synthesis” type actions increase your progress and when the progress bar is filled you finish the craft.

“Touch” actions fill a quality bar and the more full that bar is the better your odds of the item becoming “High Quality”. High Quality items typically have better stats if equipment, provide more stats if it’s food or a potion, or are used to help make it easier to reach 100% quality when crafting other items.

When in your crafter class you can press P by default to open up your action menu and see what actions you have access to.
