Editor basics

Overview of visual elements

The editor has a lot of visual elements that help you read, write, and navigate the code. Let's take a look at some of them.

Colors and fonts

General colors of visual elements in the editor are defined by the user interface theme; colors and font size of specific code elements are defined by the editor color scheme.

Line numbers

By default, editor shows line numbers in all files that you open. If you prefer not to see line numbers, clear the Show line numbers checkbox on the Editor | General | Appearance page of JetBrains Rider settings Ctrl+Alt+S.

Apart from that, you can show or hide line numbers in the current document without changing the global setting: select View | Active Editor | Show Line Numbers from the main menu.

Line wraps (soft wraps)

When working with code files, you normally do not need soft wraps if your code is properly formatted.

If you need to enable soft wraps in specific kinds of files, select Soft-wrap these files on the Editor | General page of JetBrains Rider settings Ctrl+Alt+S and add a wildcard for the corresponding file names.
