Example:

{1:NotNull: by *}

This will replace * with the input, if the input is not empty, e.g. ' by John' if the input was John.

The spacing is important, as you might add double spacing if you wrote something like You are being sued {1:NotNull:by *} for 10 dollars would output: You are being sued--for 10 dollars, with a double space in between 'sued' and 'for'. The by * part after the last colon should be translated to your language.

Example:

{0:ToLower}

Will make all letters of the input value lower case. If capitalization does not matter in your language, you can safely replace it with {0}, matching the number in the brackets, otherwise leave as is.

These represent the level of technology of a feature in a software or hardware product. An example for 3D could be versions of DirectX or OpenGL, i.e. technology that unlocks new opportunities. They are identified by the type of technology they belong to, e.g. 3D, audio, networking, and the year in which they were researched in the game.
