The autoSelect property sets or returns whether lines in a locked field highlight automatically in response to a mouseDown event and to dragging or shit-clicking (Such fields are called list fields). Automatic highlighting occurs if autoSelect, lockText, multipleLines and dontWrap are all set to true. AutoSelect is set to false when dontWrap is set to false; dontWrap is set to true when autoSelect is set to true. To learn which lines are selected, get the selectedLine of field.

You use the autoTab property to determine or change whether the specified nonscrolling field will send the tabKey message to the current tile. When the autoTab property is true, pressing Return with the insertion point in the last line of that field movies the insertion point to the next field on that tile.

The normal tabbing order for fields is as follows: if the field you are leaving is a tile, the insertion point moves to the next higher-numbered tile field or the lowest-numbered background field if no higher-numbered tile field exists; if the field you are leaving is a background field if, the insertion point moves to the next higher-numbered background field or to the lowest numbered card field if no higher-numbered background field exists.

You use the dontWrap property to determine or change the dontWrap value for a field in the current stack. When the dontWrap property of a field is set to true, the text in the specified field does not wrap at the boundary of the field. The default value for the dontWrap property is false (wrap at the boundary of the field).

You use the lockText property to prevent or allow editing of text within a field in the current stack. When the pointer is moved over an unlocked field, the pointer changes to an I-beam. Then, you can click the field and edit the text. If the field is locked (lockText is true), the cursor doesn't change , and the text cannot be edited. A locked field also receives the messages mouseDown, mouseStillDown, and mouseUp when you click it. The default value of lockText is false.

The multipleLines property returns or sets whether a user can extend the range of highlighted lines in a list field. When the multipleLines is true, the user can extend highlighted lines either by shift-clicking any point before or after the insertion point in a field or by dragging through text.

You use the selectedLines property to determine the currently selected lines of a tile or background field that has its lockText, dontWrap, autoSelect and multipleLines properties all set to true. If all of these properties are not true, the selectedLines will simply give you whatever the selectedLine property would give you for the field. The selectedLines property returns an item list (comma-delimited) containing the line numbers of the lines that are currently selected in the field.

NOTE: This function is only partially supported at this time. The number function returns the number of buttons or fields on the current tile or on its background, the number of backgrounds or tiles in the currents stack, the number of chunks of a specified kind in a designated container or text string, the number of tiles that are associated with a specified background, the number of marked tiles in the current stack, the the number of menus in the menu bar, the number of menu items in a specified menu, or the number of windows currently available.

The optionKey function returns the constant up if the Option key is not pressed, down if it is pressed.

NOTE: This function has not been implemented yet, but will be soon. The selectedChunk function returns a chunk expression describing the location of the selected text or the insertion point in a tile or background field. For selected text, it is in the form of the first character selected to last character selected of the field containing the selected text; for example, char 7 to 15 of tile field 3. If no text is selected, but the insertion point is in a field, selectedChunk returns the number of the character on either side of the insertion point in reverse order with the highest number first. For example, if the insertion point is located between characters 9 and 10 in tile field 2, selectedChunk returns char 10 to 9 of tile field 2. If nothing is selected and the insertion point is not in a field, it returns empty.

The selectedField function returns the descriptor of a field containing the selected text or the insertion point.
