Now let’s talk about how to use some of these hotkeys as an experienced terraria player
Right mouse button – I told you that you can use the right mouse button to interact and drop items while you are selecting them. Also, you can swap the equipable item with an equipped item. For example, let’s think you have a band of regeneration in your inventory.
If you right-click on it, it will be swapped with the first equipable item in your equipable list.
Also, you can do the same when you are changing armors too.
This option was helpful to me when I doing fishing quests. I was able to quickly swap angler west, pants, and hat with the armor so I can increase the fishing power.
Left shift – are you always place torches, pickaxe, axe, and glowsticks on your hot bar? There is a simple way you can use all of these items by pressing the left shift. So you don’t need to place all the items on your hot bar anymore.
Let’s think you want to use torches. Move your mouse cursor where you want to place the torch and press the left shift + left mouse button.

Let’s think you need to use the pickaxe. Only you have to do is repeat the same after you moved your mouse cursor to blocks. It is the same when you want to use the axe to cut down trees.
When you want to use glow sticks move your mouse cursor away (more than your player’s blocks placing range) and press shift + left mouse button. But you can just press shift + Mouse click to throw them if you are under the water.

Left Alt – you can favorite items using this option. It will help you to block quick trash, stacking, and selling. Mostly it was helpful for me when I using the ‘quick stack to nearby chests’ option.
Left Ctrl – If you normally press the left ctrl button, you can enable the smart cursor mod. This is very helpful when you are mining and building.
Also if you press Left Ctrl + left mouse to an item in the inventory, you can quick trash it and quickly sell it while you are viewing and any NPC’s shop.
