Text Editor tab

Specifies the text and style for individual text feature instances on annotation layers.

Style Panel

Style
Click the arrow next to the current style to see available styles. To select a style, click its name. Your changes affect all text instances on the current text layer.
Size
Select the text to resize, and then select a size from the drop-down or type a size in the field.

Formatting Panel

Character Styles
Specify the font, color, bold, italic, under- and overline, upper- or lowercase, background mask, angle, width, and tracking. Use the Stack option for fractions and tolerance units.

Paragraph Panel

Paragraph Styles
Specify the vertical and horizontal justification, add bullets or numbering, and adjust line spacing within paragraphs. To make multiple paragraphs into a single paragraph, select them and click Combine Paragraphs.

Insert Panel

Columns
Specify no columns (the default); dynamic columns (Auto Height adjusts the column size to the text it contains; Manual Height maintains a column height that you set); or static columns (specify the number of columns).
Symbol
Select the symbol to insert from the drop-down list.
Field
Click Field to see a dialog box with a list of AutoCAD fields you can insert. Select a field to see its formatting options.

Spell Check Panel

Spell Check
Determines whether your spelling is checked as you enter text. Click this option to turn it on or off.
Edit Dictionaries
Edit any of the supported language dictionaries.
Check Spelling Settings
Click the angle arrow to specify spell checking preferences.

Tools Panel

Find And Replace
Searches for specified text strings and replaces them with new text.
Import Text
Import any file that is in ASCII or RTF format. Imported text retains its original character formatting and style properties, but you can edit and format the imported text in the editor. After you select a text file to import, you can replace either selected text or all text, or append the inserted text to text selected within the text boundary. The file size for imported text is limited to 32 KB.

The editor automatically sets the text color to BYLAYER. When black characters are inserted and the background color is black, the editor automatically changes to white or the current color.

Note: A Microsoft Excel spreadsheet imported into a drawing is truncated at 72 rows unless the spreadsheet was created in Microsoft Office 2002 with Service Pack 2 installed. The same limitation applies when the drawing that contains the OLE object is opened on a system with an earlier version of Microsoft Office installed; the spreadsheet is truncated.
Auto CAPS

Converts all new and imported text to uppercase. AutoCAPS does not affect existing text. To change the case of existing text, select the text and right-click.

Options Panel

Undo/Redo
Reverses or restores actions in the Text Editor ribbon contextual tab, including changes to either text content or text formatting.
Ruler

Displays a ruler at the top of the editor. Drag the arrows at the end of the ruler to change the width of the mtext object. Also displays height and column grips when column mode is active.

You can also select tabs from the ruler. Clicking the Tab Selection button changes tab styles from left, center, right, and decimal. Once you make your selection, you adjust the corresponding tab in the ruler or in the Paragraph dialog box.
