Shatter
The Shatter menu can be found with the [Shatter...] button in the main General Tool menu. This operation breaks blocks, causing particles and sound.

The block selection menu at the bottom of the menu starts the Shatter operation once you select a block with it. Selecting a block in the menu the [Replace...] button opens also starts the opreation.
Drop Items
The [Drop Items] option toggles whether to drop items from shattered blocks.
Replace
The [Replace...] button opens a menu where you can choose a certain block to replace ([Normal]), or a certain block to not replace ([Exclude]). Selecting a block in this menu starts the Shatter operation.
Seeing as this operation removes existing blocks, the [Keep] option, which normally makes the operation only replace blocks such as air or water, has no effect on it.
