Appearance

Use this page to customize the appearance of the editor.

Item	Description
Caret blinking (ms)	Select this checkbox to make the caret blink with the specified period (in milliseconds).
Use block caret	Select this checkbox to have the block caret applied in the Insert mode and the usual caret applied in the Overwrite mode. Clear this checkbox to have the usual caret applied in the Insert mode and the block caret applied in the Overwrite mode.
Show hard wrap and visual guides (configured in Code Style options)	Select this checkbox to have a thin vertical line at the right margin of the editor displayed. Refer to the description of the Code Style settings.
Show line numbers	Select this checkbox to have line numbering shown in the editor gutter.
Show method separators	Select this checkbox to have thin lines displayed in classes, scripts or RSpec, TestUnit and SpecTest tests to separate methods and examples.
Show whitespaces	Select this checkbox to have RubyMine display whitespaces or tabs (depending on the Code Style settings). You can select the following options: Leading: select this checkbox to add whitespaces before your code line. Inner: select this checkbox to display whitespaces inside the line of your code. Trailing: select this checkbox to display whitespaces after the code line.
Show indent guides	Select this checkbox to display vertical lines in the editor to indicate positions of indents and thus facilitate typing, manual formatting, reading, and maintaining code.
Show intention bulb	Whenever RubyMine detects that your code can be modified or improved, a light bulb icon appears on the current line in the editor: for intention actions and for quick-fixes. Clear this checkbox if you don't want to see these icons. You can still access the list of available actions and quick-fixes by pressing `Alt+Enter`.
Show code lens on scrollbar hover	Select this checkbox to enable the lens mode.
Render documentation comments	Select this checkbox to always render documentation comments as text paragraphs with proper formatting and links right in the editor. Rendered comments are easier to read, and they don't overload your code with extra tags.
Enable HTML/XML tag tree highlighting	Select this checkbox to show the hierarchy of tags highlighted with different colors. If this option is enabled, you can define the following options: Levels to highlight: specify the depth of hierarchy to be highlighted. Opacity: specify brightness of highlighting Highlighting is activated when there is more than one tag with the same name in the hierarchy.
Show CSS color preview as background	If this checkbox is selected, the background of the color value shows the color preview: By default, RubyMine also shows color preview icons in the gutter. Clicking such icon invokes the Color Picker where you can change the color value. To hide these gutter icons, clear the Color preview checkbox on the Gutter Icons page. See also Changing color values.
Highlight RDoc and ruby in comments	If this checkbox is selected, the keywords are highlighted in comments. Otherwise, they are displayed as plain text. Changing state of this checkbox takes effect upon RubyMine restart only.
Show closing labels in Dart source code	This feature is only supported, when the Dart plugin is installed! By default, RubyMine inserts autogenerated comments (closing labels) after the closing parentheses of objects within the `build()` method in Dart code. Clear the checkbox to suppress adding closing labels.
