How can I place the torches in terraria?

Just got the new game and noticed it's tricky to place torches. I have placed a torch or two but I don't know what I did to place them. Is there an easier way to place the torches besides clicking a thousand times?

You can place torches on blocks (floors and "walls") and actual wall-blocks. The easiest way to place a torch is to hold SHIFT (default) and click near a block, either on its side or top of it, but make sure you don't click the block. If the background is not sky, rocky or hell, you can click anywhere on the background to place a torch.

Also make sure you're close enough, you can only place a torch (or a block) from 5 blocks away (horizontal) and 3 blocks away (vertical).

Torches can be placed adjacent to blocks or on background tiles.
