RubyMine 6.3.0 Web Help

RubyMine editor is a powerful tool for creating and modifying source code. As any other IDE editor, it supports basic features like bookmarks, breakpoints, syntax highlighting, code completion, zooming, folding code blocks, etc. There are, however, plenty of advanced features like macros, highlighted TODO items, code analysis, intention actions, intelligent and fast navigation, and a lot more.

To configure your editing environment, use the Editor settings page and its child pages. There is also a Quick Switch Scheme command that lets you change color schemes, themes, keymaps, etc. with a couple of keystrokes.

The editor is tab-based. All operations with the editor tabs are available from the context menu of a tab, or from Window | Editor tabs node of the main menu.

When you open a file for editing, it opens in its own tab. The editor you are currently working in, is the active editor. You can change behavior of the active editor using the commands under View | Active Editor node of the main menu.


You always return the focus to the active editor from any tool window by pressing the EscapeEscapeEscapeEscapeEscape, Escape or Ctrl+GEscapeEscapeEscapeEscapeEscapeEscapeEscapeEscape key.

This is the bar to the right from the editing area, showing the green, red or yellow box on its top depending on whether your code is okay, or contains errors or warnings. This bar also displays active red, yellow, white, green and blue navigation stripes that let you jump exactly to the erroneous code, changed lines, search results, or TODO items.
