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

ItemDescription
HomeWhen this check box is selected, on pressing Home, the caret is positioned at the first non-space 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)When this check box is selected, on pressing End in an empty line, the caret is positioned with the indent, which IntelliJ IDEA assumes to be reasonable in the current code point (indentation is based on the current Code Style Settings).
Insert pair bracketSelect this check box to have IntelliJ IDEA automatically add a closing round or square bracket for each typed opening round or square bracket, respectively.
Insert pair quoteSelect this check box to have IntelliJ IDEA automatically add a closing single or double quote for each typed opening single or double quote, respectively.
Reformat block on typing "}"If this check box 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 check box to have IntelliJ IDEA 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 (Ctrl+Right/Ctrl+Left)
  • Caret Move with Selection (Ctrl+Shift+Right/Ctrl+Shift+Left)
  • Select Word at Caret (Ctrl+W)
  • Delete to Word Start/End (Ctrl+Backspace and Ctrl+Delete respectively)
  • Double-clicking

The following editor actions work in a mode opposite to the one established by the Use 'CamelHumps' words setting:

  • Move Caret to Previous Word in Different "CamelHumps" mode
  • Move Caret to Previous Word with Selection in Different "CamelHumps" mode
  • Move Caret to Next Word in Different "CamelHumps" mode
  • Move Caret to Next Word with Selection in Different "CamelHumps" mode
  • Delete to Word End in Different "CamelHumps" mode
  • Delete to Word Start in Different "CamelHumps" mode

For example, If the check box is selected, the action Move Caret to Next Word in Different "CamelHumps" mode moves the caret to the end of word; if the check box is not selected, then the caret moves to the next CamelHump.

These actions have no default keyboard shortcuts, and are not included in the menus. Thus, they can be invoked by pressing Ctrl+Shift+A:

(Refer to the section Navigating to Action)

You can bind them with the shortcuts of your choice as described in the section Configuring Keyboard Shortcuts.

Surround selection on typing quote or braceIf this check box is selected, the selected text on typing a quote, double-quote or brace, will be surrounded with these characters. If this check box is not selected, then the typed quotes, double-quotes or braces will replace the selection.
Add multiple carets on double Ctrl/ with arrow keysIf this check box is selected, then:
  • pressing Ctrl (for Windows or *NIX) or (for Mac OS) twice plus up/down arrow keys leads to creating multiple carets.
  • pressing Ctrl (for Windows or *NIX) or (for Mac OS) twice plus left/right arrow keys or Home/End leads to creating a selection.
EnterUse this area to define the actions to be invoked by pressing Enter.
  • Smart Indent - select this check box to have IntelliJ IDEA add a new line and position the caret in it, with the indent that IntelliJ IDEA assumes to be reasonable in the current point of code (indentation is based on the current Code Style Settings).

    If the check box is cleared, upon pressing Enter in a blank line, IntelliJ IDEA adds a new line and positions the caret at the current non-space character column.

  • Insert pair '}' - select this check box to have IntelliJ IDEA automatically position a closing brace } at the proper column when Enter is pressed in an empty line. In this case IntelliJ IDEA seeks backward for the nearest unclosed opening brace { and places the closing one at the corresponding indentation level.
  • Insert documentation comment stub - this check box defines the behavior on pressing Enter after an opening documentation tag.
    • If this check box is selected, IntelliJ IDEA generates a documentation comment stub. For the method comments, this stub contains the required tags (@param tags for each method parameter, @return, or @throws). Refer to Creating Documentation Comments and Creating JSDoc Comments for details.
    • If this check box is not selected, only the closing tag is generated.
BackspaceUse this drop-down 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 indentation
Reformat on pasteUse this drop-down 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 currentCode Style Settings.
XML/HTMLIn this area, define the actions to be invoked automatically when editing XML or HTML code.
  • Insert closing tag on tag completion: select this check box to have IntelliJ IDEA automatically insert a closing XML or HTML tag upon entering the corresponding opening one.
  • Insert required attributes on tag completion: select this check box to have IntelliJ IDEA display a template with all mandatory attributes of the typed tag.
  • Insert required subtags on tag completion: select this check box to have IntelliJ IDEA display a template with all mandatory subtags.
  • Start attribute on tag completion: select this check box to have IntelliJ IDEA display a template with the first mandatory attribute of the typed tag.
  • Add quotes for attribute value on typing '=': select this check box to have IntelliJ IDEA automatically add quotes for the value of the attribute that you are currently typing.
  • Auto-close tag on typing '</': select this check box to automatically add a closing tag after entering </. Clear this check box to turn off such auto-completion.
  • Simultaneous <tag></tag> editing:
    • When this check box is selected and you edit an opening tag the corresponding closing tag is automatically changed accordingly.
    • If this check box 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.

    This check box controls the behaviour of IntelliJ IDEA in the following contexts:

    • HTML files
    • HTML injections within JavaScript code
    • HTML with templates Handlebars/Mustache templates
    • Handlebars/Mustache template files with the extension .hbs
    • XML, XHTML files
    • DTD files
    • JSX files
    • JSP files
    • HTML injections in PHP files

CSSIn this area, define the selection of CSS identifiers/classes:
  • Select whole CSS identifier on double-click: If this check box is selected, double-click on a CSS identifier or class name selects the entire name up to the prefix:
    select_css_identifier

    If this check box is not selected, double-click on a CSS identifier or class name selects a portion of a name up to the nearest hyphens:

    select_css_identifier1
AngularJSUse this area to define the behavior of AngularJS:
  • Auto-insert white space in the interpolation: If this check box is selected, a white space is automatically inserted between the braces: {{ }}.
    If this check box is not selected, the white space is not inserted: {{}}.
JavadocIn this area, define the behavior of the closing tags in Javadoc.
  • Automatically insert closing tag - select this check box to make IntelliJ IDEA insert closing tag automatically, after typing >. So doing, the caret rests inside the tag. For example, if you type <b>, the closing tag</b> will be generated automatically.
Insert pair '%>' on Enter in JSPSelect this check box to have IntelliJ IDEA automatically position the opening angle bracket < at the proper column when entered in an empty line in JSP code. In this case IntelliJ IDEA seeks backward for the nearest unclosed angle bracket and places a closing one > at the corresponding indentation level.
PHPUse this area to define the behavior of PHP:
