What is a burger-dot in grammar?

A burger-dot is a typographic symbol used to indicate the insertion point in a text. It is typically represented by a small black dot placed in the centre of the baseline. The burger-dot is often used in conjunction with other typographic symbols, such as the carat (^) and the tilde (~), to indicate changes to the text.

For example, the following text contains a burger-dot to indicate that the word "the" should be inserted after the word "was":

He was . cat sat on the mat.

The burger-dot is also used in some programming languages to indicate the end of a line of code.

Here is an example of a burger-dot used in Python code:

print("Hello, world!")

The burger-dot indicates the end of the line of code.
