Smart Keys

Use this page to enable or disable specific smart keys and to define which actions you want to be invoked automatically.

Item	Description
Home moves caret to first non-whitespace character	When this checkbox is selected, on pressing `Home`, the caret is positioned at the first non-whitespace character of the current line. Pressing `Home` subsequently moves the caret from the Smart Home position to the first column and back.
End on blank line moves caret to indent position	When this checkbox is selected, on pressing `End` in an empty line, the caret is positioned with the indent, which RubyMine assumes to be reasonable in the current code point (indentation is based on the current Code Style Settings).
Insert pair brackets (), [], {}, <>	Select this checkbox to have RubyMine automatically add a closing bracket for each typed opening bracket, respectively.
Insert pair quote	Select this checkbox to have RubyMine automatically add a closing single or double quote for each typed opening single or double quote, respectively.
Reformat block on typing '}'	If this checkbox is selected, then, on typing the closing curly brace, the enclosed code block is reformatted automatically if the formatting of this code block does not match the selected code style.
Use "CamelHumps" words	Select this checkbox to have RubyMine discern separate words within CamelHump names. Words within a name should start with a capital letter or an underscore. This option impacts some editor actions, for example: Caret Move `Control+ArrowRight`/`Control+ArrowLeft` Caret Move with Selection (`Control+Shift+ArrowRight`/`Control+Shift+ArrowLeft`) Select Word at Caret `Control+W` Delete to Word Start/End (`Control+Backspace` and `Control+Delete` respectively) Double-clicking (if Honor "CamelHumps" word settings when selecting using double click is enabled).
Honor "CamelHumps" words settings when selecting on double click	Select this checkbox to have RubyMine invoke the CamelHumps selection when words are selected by double-clicking. This feature works only if the Use 'CamelHumps' words option is enabled.
Surround selection on typing quote or brace	If this checkbox is selected, the selected text on typing a quote, double-quote or brace, will be surrounded with these characters. If this checkbox is not selected, then the typed quotes, double-quotes or braces will replace the selection.
Add multiple carets on double `Control` with arrow keys	If this checkbox is selected, then: pressing `Control` plus up/down arrow keys leads to creating multiple carets. pressing `Control` plus left/right arrow keys or Home/End leads to creating a selection. For more information, see the Multicursor section.
Jump outside closing bracket/quote with Tab when typing	If this checkbox is selected, pressing `Tab` when typing inside brackets/quotes will move the caret outside the closing bracket/quote. If this checkbox is not selected, pressing `Tab` will insert the `Tab` character. Note that this only works on initial typing: during subsequent editing, pressing `Tab` inside brackets/quotes will insert the `Tab` character.
Enter	Use this area to define the actions to be invoked by pressing `Enter`. Smart indent: select this checkbox to have RubyMine add a new line and position the caret at it, with the indent that RubyMine assumes to be reasonable in the current point of code (indentation is based on the current Code Style settings). If the checkbox is cleared, upon pressing `Enter` in a blank line, RubyMine adds a new line and positions the caret at the current non-space character column. Insert pair '}': select this checkbox to have RubyMine automatically position a closing brace `}` at the proper column when `Enter` is pressed in an empty line. In this case RubyMine seeks backward for the nearest unclosed opening brace `{` and places the closing one at the corresponding indentation level. Close block comment: unselect this checkbox to disable the automatic closure of the block comment when hitting `Enter`. Insert documentation comment stub: this checkbox defines the behavior on pressing `Enter` after the opening documentation comment. This functionality works only for JavaScript , Java, Groovy, and Swift. If this checkbox is selected, RubyMine generates a documentation comment stub. For the function comments, this stub contains the required tags (`@param` tags for each parameter declared in the signature, and `@return`). Refer to , JSDoc comments for details. If this checkbox is not selected, only the closing part of the comment is generated. Note that this checkbox refers to JavaScript and other languages that have special beginning of documentation comments. This checkbox does not refer to Ruby.
Unindent on Backspace	Use this list to define the actions to be invoked by pressing `Backspace` key. The available options are: Disabled: pressing `Backspace` returns the caret by one position at a time. To nearest indent position To proper indent position
Reformat on paste	Use this list to specify how to place pasted code blocks. The available options are: None: the pasted code is inserted at the caret location as plain text without any reformatting or indenting. Indent block: the pasted code block is positioned at the proper indentation level, according to the current Code Style Settings, but its inner structure is not changed. Indent each line: each line of the pasted code block is positioned at the proper indentation level, according to the current Code Style Settings. Reformat block: the pasted code block is reformatted according to the current Code Style Settings. This feature is applicable to lines that contain the trailing line feed characters.
Reformat again to remove custom line breaks	When this option is enabled, invoking the Reformat Code `Control+Alt+L` or Reformat File `Control+Alt+Shift+L` actions the second time after the code has been reformatted will remove custom line breaks. When the option is disabled, invoking the actions the second time opens a dialog in which you need to confirm removing line breaks first. Click Don't ask again in the dialog to never remove custom line breaks when you reformat code for the second time.
Kotlin	Use this area to configure the smart keys options for Kotlin. Convert pasted Java code to Kotlin: select this option to convert any Java code to Kotlin on paste. RubyMine displays the Convert Code from Java dialog. If you don't want RubyMine to show the dialog, select the Don't show Java to Kotlin conversion dialog on paste option.
Start ruby interpolation in strings on #	If this checkbox is selected, after pressing `#`, RubyMine will automatically insert opening and closing curly braces, with the cursor resting inside. If this checkbox is cleared, then after typing `#`, you have to type the opening curly brace, to initiate Ruby interpolation. This is the default behavior. Note that all sorts of Ruby coding assistance (code completion, syntax and error highlighting, intention actions and quick fixes) are available in the code interpolation.
Continue comments on Enter	If you are editing a comment in the Ruby file, pressing `Enter` moves the caret at the beginning of the next line and adds the `#` character automatically. You can use this option to disable this capability.
AngularJS	Use this area to define the behavior of AngularJS: Auto-insert white space in the interpolation: If this checkbox is selected, a white space is automatically inserted between the braces: `{{ }}`. If this checkbox is not selected, the white space is not inserted: `{{}}`.

HTML/CSS

Use this page to configure the editor behavior for HTML, XML, and CSS.

Item	Description
XML/HTML	In this area, define the actions to be invoked automatically when editing XML or HTML code. Insert closing tag on tag completion: select this checkbox to have RubyMine automatically insert a closing XML or HTML tag upon entering the corresponding opening one. Insert required attributes on tag completion: select this checkbox to have RubyMine display a template with all mandatory attributes of the typed tag. Insert required subtags on tag completion: select this checkbox to have RubyMine display a template with all mandatory subtags. Start attribute on tag completion: select this checkbox to have RubyMine display a template with the first mandatory attribute of the typed tag. Add quotes for attribute value on typing '=' and attribute completion: select this checkbox to have RubyMine automatically add quotes for the value of the attribute that you are currently typing. Auto-close tag on typing '</': select this checkbox to automatically add a closing tag after entering </. Clear this checkbox to turn off such auto-completion. Simultaneous <tag></tag> editing: When this checkbox is selected and you edit an opening tag the corresponding closing tag is automatically changed accordingly. If this checkbox is cleared, editing the opening tag does not affect the closing tag which remains unchanged. As a result, the opening and closing tags do not match and the entire construct is underlined as erroneous. The Simultaneous <tag></tag> editing checkbox controls the behavior of RubyMine in the following contexts: HTML files HTML injections within JavaScript code HTML with Handlebars/Mustache templates Handlebars/Mustache template files with the extension .hbs XML, XHTML files DTD files JSX files
CSS	In this area, define the selection of CSS identifiers/classes: Select whole CSS identifier on double-click: if this checkbox is selected, double-clicking a CSS identifier or class name selects the entire name up to the prefix. For example, double-clicking `gray` within `<div class="text-gray-600">` select the whole class name `text-gray -600`: If this checkbox is cleared, double-clicking a CSS identifier or class name selects a portion of the name up to of within the nearest hyphens:
