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

Item	Description
Home	When 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 bracket	Select 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 quote	Select 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 brace	If 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 keys	If 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.
Enter	Use 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. For the function comments, this stub contains the required tags (`@param` tags for each parameter declared in the signature, and `@return`). Refer to , Creating JSDoc Comments for details. If this check box is not selected, only the closing tag is generated. Note that this check box refers to JavaScript, Java and the other languages that have special beginning of documentation comments.
Backspace	Use 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 paste	Use 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. This feature is applicable to lines that contain the trailing line feed characters.
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 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
CSS	In 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: 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:
AngularJS	Use 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: `{{}}`.
Javadoc	In 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.
SQL	Insert string concatenation on Enter. You may want to turn this option off, if the DBMS you are working with supports multiline string literals: Say, there is the following fragment for PostgreSQL `text` value `notes`: `SET notes = 'Lightest element'` and the cursor is in front of the word `element`. If the option is on, and you press `Enter`, the fragment will change to: `SET notes = 'Lightest ' \|\| 'element'` Otherwise, the fragment will change to: `SET notes = 'Lightest element'` Qualify object on code completion. The selected option defines how the name of an object is inserted in the editor when using the code completion suggestion box. Always. The qualified object names are always used, i.e. `<schema_name>.<object_name>`. On collisions. The qualified object name is used only if the short name is ambiguous, e.g. when there is the object with the same name in more than one schema. Never. The unqualified object names are always used.
Insert pair '%>' on Enter in JSP	Select 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.
PHP	Use this area to define the behavior of the editor in the PHP context: Enable smart function parameter completion: when this check box is selected, you can use the “automatic” live template that provides completion lists for the parameters passed into functions, methods, or class constructors. To invoke the magic live template, type the params keyword as the first parameter in the call of the function, method, or class: IntelliJ IDEA displays a live template where the parameters are automatically completed with the variable names defined in the function declaration. To move to the next parameter, press `Enter` or `Tab`. To move to the previous parameter, press `Shift+Tab`. The completion list contains variables from a local scope in the next order: with the same type, with a similar name, defined nearby. You can always switch to the usual completion mode by pressing `Ctrl+Space` or just typing anything which is not in the list. Variables with similar names are inserted automatically. Select variable name without $ sign on double click: when this check box is selected, only the variable name that follows the `$` sign is selected on double click or pressing `Ctrl+W`. This is helpful if you often need to copy variable names without `$`: just double-click and copy the selection. If you still need a variable name with `$` selected, place the cursor before the `$` sign and double click it or press `Ctrl+W`.
