Behavior & Display preferences

Language

Select the programming language to which the preferences will apply; the default is All Languages. If you select a specific language, the changes will apply only to that language.

Use custom settings - this checkbox appears only if Language is not set to All Languages. This box must be checked to make any changes in the settings for the selected language.

In order to enable the Language-Specific tab, Language must be set to a specific language.

Behavior Preferences

Tabs:

• Tab size - default size is four characters.
• Insert spaces for tab- if checked, tab size whitespaces are inserted into the document instead of the tab character when the Tab key is pressed.

Indentation:

• Smart tab - if checked, when the Tab key is pressed the cursor is moved to align with the first character following a whitespace on the previous non-blank line.
• Smart backspace - if checked, backspace intelligently through whitespace.
• Smart indent - if checked, indent code based on the indentation of the previous line. New lines are indented to the first non-blank character of the line above.
• Strip trailing white spaces - remove trailing whitespace from the file

Automatically Close: If checked, the closing symbol will be added to each of these:

• String
• Single quotes
• Parenthesis
• Curly braces
• Square brackets
• Angle brackets

Smart Key Options:

• Smart home - if checked, the Home key moves the cursor to the left of the first non-blank character on the line.
• Smart end - if checked, the End key moves the cursor to the right of the last non-blank character on the line.

New Document Format: Sets the default line ending for new text documents:

• Windows - Use the CRLF end-of-line format, as used by Windows and most other early non-Unix and non-IBM operating systems.
• UNIX/Mac - Use the LR end-of-line format, as used by UNIX-like systems including Mac OS X.
• Mac 9 - Use the CR end-of-line format, as used by Mac OS up to version 9.
