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.

JetBrains Rider: visual elements of the editor

Line numbers are displayed by default, but you can hide them globally or for the current document.
Action indicators show that one or more actions are available for the current caret position. To see the available actions, press Alt+Enter or click the indicator.
Code vision adds various helpful information to types and type members.
Inlay hints are automatically inserted into your code to improve its readability.
Bookmarks let you mark code lines where you want to return later.
VCS line status highlighting identifies modified code lines if version control integration is enabled.
Breakpoints let you suspend program execution at the marked statement.
Code folding adornments help you expand and collapse code elements.
Breadcrumbs at the bottom of the editor show and allow navigating the structural path from the top of the file to the current caret position.

Syntax and error highlighting — while syntax highlighting improves the readability of clean code, error highlighting helps to visualize detected code issues.
Editor tabs help you manage multiple open documents.
File status indicator displays the number of code issues detected in the current file.
Error stripe shows different code items as clickable markers relative to their locations in the document.
Right margin visualization helps to see the maximal text column width used by the code formatter.
Quick documentation shows symbol information and documentation.
'Pencils' widget is a single entry point where you can configure highlighting and visual helpers for your code.

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.
