ItemDescription
Mouse
Honor "CamelHumps" word settings when selecting using double clickSelect this check box to have IntelliJ IDEA invoke the CamelHumps selection when words are selected by double-clicking.

This feature works only if the Use 'CamelHumps' words option is enabled.

Change font size (Zoom) with Ctrl/Command+Mouse WheelIf this check box is selected, a particular editor font size can be changed by rolling the mouse wheel while holding the Ctrl/⌘ key.

This check box also affects font size in quick documentation lookup.

If this option is unchecked, rolling the mouse wheel while holding the Ctrl/⌘ key scrolls the editor.

Enable Drag'n'Drop functionality in editorIf this check box is selected, you can drag-n-drop code fragments in the editor. Refer to Using Drag-and-Drop in the Editor.
Soft Wraps
Use soft wraps in editorIf this check box is selected, soft wraps (or word wraps) are used in the editor.

The horizontal scroll bar is not normally shown when this option is enabled. However, in certain cases, when a line cannot be "soft-wrapped", the horizontal scroll bar still appears (for example, if a line consists of a single string that is wider than the visible area.)

Use original line's indent for wrapped partsSelect this check box to use custom indentation for soft wraps on resizing the editor or console. Specify the indent value in the Additional shift text field on the right.
Show soft wrap indicators for current line onlyIf this check box is selected, the soft wrap characters soft_wraps soft_wrap will be shown in the active logical line only.

Otherwise, soft wraps characters will be shown at the end of each line, and at the beginning of each next line.

Virtual Space
Allow placement of caret after end of lineIf this check box is cleared, the caret never rests after the last symbol in a line.
Allow placement of caret inside tabsSelect this check box to allow placing the caret inside tab characters. The reason is that each tab character shows in the editor as a set of 'virtual' space characters.
Show virtual space at file bottomIf this check box is selected, the currently edited line (even if it is the final line) can be scrolled to the top of the screen. IntelliJ IDEA adds the necessary amount of virtual lines.
Other
Strip trailing spaces on SaveFrom this drop-down list, select the mode in which IntelliJ IDEA will handle trailing spaces in the end of lines on file saving:
  • Modified lines - Strips trailing spaces only in the end of modified lines.
  • All - Strips trailing spaces in all lines.
  • None - Does not strip trailing spaces.
Ensure line feed at file end on Save Select this check box to have IntelliJ IDEA automatically add an empty line in the end of a file during the save procedure.
Show quick documentation on mouse moveSelect this check box to show quick documentation for the symbol at caret. The quick documentation pop-up window appears after the specified delay.
Highlight modified lines in gutterSelect this check box if you want added/modified lines to be highlighted with a color stripe in the left editor gutter.
Different color for lines with whitespace-only modificationsThis option only becomes available if the Highlight modified lines in gutter option is enabled.

Select this check box if you want lines where only whitespaces were added/removed to be highlighted with a different color from lines with more significant modifications.

Highlight on Caret Movement
Highlight matched braceSelect this check box to have IntelliJ IDEA highlight pairs of opening/closing braces when you position the caret right before the opening or right after the closing one. It also works for HTML and XML tags.
Highlight current scopeSelect this check box to have IntelliJ IDEA highlight the available scope for the code typed in the current caret location.
Highlight usages of element at caretSelect this check box to have IntelliJ IDEA highlight all usages of the element at which the caret is currently positioned.
Formatting
Show notification after reformat code actionSelect this check box to show a notification with changes in your code and a shortcut to the Reformat Code dialog every time you try to reformat the code. Otherwise, IntelliJ IDEA will reformat code silently.
Show notification after optimize imports actionSelect this check box to show notification with changes in your code. Otherwise, IntelliJ IDEA will optimize imports silently.
Scrolling
Smooth scrollingSelect this check box to enable smooth scrolling in the editor.
Prefer scrolling editor canvas to keep caret line centeredClick this option to choose scrolling editor canvas and keeping the caret in place.

Keeping the caret in place and scrolling the editor canvas can be helpful in course of debugging session. As you step through the lines of code, the editor canvas scrolls, while the line at caret is always in the center of the screen.

Prefer moving caret line to minimize editor scrollingClick this option to choose moving the caret.

When you step through the lines of code during the debugging session, the caret moves down, and the editor canvas doesn't scroll until the caret line reaches the bottom of the screen.

Refactorings
Enable in-place mode Select or clear this check box to enable or disable in-place refactorings for Java.

The in-place in connection with the refactorings means specifying all or most of the information necessary for the refactoring by typing, right in the editor. All the affected code fragments are highlighted and change as you type. If appropriate, additional refactoring options are selected in corresponding option boxes.

The in-place refactoring mode is available for the following refactorings:

If this check box is not selected, the refactoring settings for all of the refactorings are specified in the corresponding dialogs.

Preselect old nameIf this check box is selected, the old name of a symbol is selected when the Rename refactoring is invoked for that symbol.
preselect_on

If check box is not selected, the symbol being renamed is not selected.

Show inline dialog for local variablesSelect this check box if you want to display a confirmation dialog for the "Inline local variable" refactoring.
Limits
Maximum number of contents to keep in clipboardIn this text box, specify how many code blocks can be kept in clipboard.
Recent file limitIn this text box, specify how many file names can be included in the list of recent files.
Rich-text copy
Copy as rich text by defaultSelect this check box to copy a rich text from the editor to any other editor that recognizes RTF.
Note that you can override this option if you select Copy as Plain Text from the context menu in your editor and vice versa, using the Copy as Rich Text option from the context menu overrides the unselected check box in the editor settings.
Color schemeUse this drop-down list to select a color scheme for the text copy. You can select from the following options:
  • Default
  • Active scheme
  • Darcula
Error highlighting
Error stripe mark min height (pixels)In this text box, specify the minimum size of the error and warning stripes.
Autoreparse delay (ms)In this text box, specify the time period after which IntelliJ IDEA starts reparsing the entered text.
'Next Error' action goes to high priority problems onlySelect this check box to have IntelliJ IDEA pass through the highest priority problems only (for example, errors), when executing Navigate | Next/Previous Highlighted Error command (F2/Shift+F2).

Clear this check box to have IntelliJ IDEA pass through all the existing problems (for example, errors and warnings) sequentially.

Suppress with @SuppressWarnings (for 5.0 only)Select this check box to have @SuppressWarnings implemented as an annotation.

Clear this check box to have @SuppressWarnings implemented as a JavaDoc comment.
