Although MLTE does not handle any menu except for the Font menu, it provides applications with all the necessary functionality and information to support the standard text editing menus as specified in Macintosh Human Interface Guidelines and the Mac OS 8 Human Interface Guidelines. MLTE supports the Undo, Redo, Cut, Copy, Paste, Clear, and Select All items in the Edit menu, but does not support Publish and Subscribe.
MLTE supports undo for the Cut, Copy, Paste, and Clear commands as well as applying a font, size, or style to a non empty selection. However, applying a font, size, or style to an insertion point cannot be undone. Undo cannot be applied to a Select All command because Select All is a selection operation.
An uninterrupted sequence of keystrokes, whether done as standard input on a keyboard or as inline input using an input method, is treated as a single typing command for purposes of the Undo command. Events that interrupt a typing sequence include selection operations (except for those handled by input methods), deactivating a window, printing, or any undoable command other than typing.
MLTE supports the use of checkmarks and dashes in text-related menus, such as Size and Style menus. It also supports the use of items that increment or decrement size, and an "Other" item in a Size menu.
