Check mark is a pretty popular text symbol used to indicate the concept "yes" from the times when ASCII encoding was developed. And you can type it right from your keyboard. I'll show you how to do it by using different techniques depending on your Operating System and tastes.
What tick signs mean
A tick (also known as a check mark or check) is a mark used to indicate the concept "yes", for example "yes; this has been verified", "yes; that is the correct answer", "yes; this has been completed", or "yes; this [item or option] applies to me". The x mark is also sometimes used for this purpose (most notably on election ballot papers), but otherwise usually indicates "no", incorrectness, or failure. As a verb, to tick (off) or to check (off) means to add such a mark. It is quite common, especially on printed forms, printed documents, and computers (see check box), for there to be squares in which to place ticks. Read Wikipedia article to find out more about its meaning and using.
