The purpose of text editors

Now I will be describing how these text editors are important.

1. Character. These are all the things that we see when we type up our work. Letters, numbers and punctuation marks are all classed as characters.
2. Point size. This is the height of the font which is expressed in points
3. Kerning. This is when we adjust the spacing between letters or characters in a piece of text to be printed.
4. Leading. This is the amount of blank space between lines of print.
