JetBrains Rider 2021.1 Help

Editor Basics

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 by clearing the Show line numbers checkbox on the Editor | General | Appearance page of JetBrains Rider settings Ctrl+Alt+S.

  • Code folding adornments help you expand and collapse code elements.

  • 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.

  • Breakpoints let you suspend program execution at the marked statement.

  • Bookmarks let you mark code lines where you want to return later.

  • Syntax and error highlighting— while syntax highlighting improves the readability of clean code, error highlighting helps to visualize detected code issues.

  • 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.
