The preferences grouped under the "Editor" option of the Preferences dialog box allow you to customize the editor to suit your needs.

Auto Indent: Positions the cursor under the first non-empty character of the preceding non-empty line when you press Enter.

Smart Tabs: Tabs to the first non-whitespace character in the preceding line.

Backspace Unindents: Aligns the insertion point to the previous indentation level (outdents it) when you press Backspace, if the cursor is on the first nonblank character of a line.

Show Line Numbers: Displays the line numbers for the file being edited in the "Gutter" area.

Group Undo: Undoes your last editing command as well as any subsequent editing commands of the same type.

Cursor Beyond EOF/EOL: Each allows the cursor to be placed at a point after the last line of the file (EOF) or beyond the last character of a line (EOL).

Display Special Characters: Shows formatting characters like paragraph marks used in some word processors.

Double Click Line: Double-clicking on a line selects the entire line.

Find Text at Cursor: When the Find command is executed, the text currently under or next to the cursor is selected in the "Find" option.

Disable Dragging: Disables the dragging of blocks of text within a file.

Highlight URLs: Will automatically make links of http:// or www. or e-mail addresses that can be clicked within a document to open the related program within Windows.

Word Wrap: Ensures that text beyond the margin of a line automatically flows on to the next line so that all the text displays on screen rather than disappearing off it.

Gutter: This is a strip down the leftmost side of an editor, which provides line numbers and bookmarks for the file being edited.

Tab Stops: Set the character columns that the cursor will move to each time you press Tab.
