构造函数

TextareaMovementForKey#

func TextareaMovementForKey(key ui.Key, modifiers ui.Modifiers) (movement TextareaMovement, extend bool)

TextareaMovementForKey says which movement a key asks for in a multiline editor, and whether it extends the selection (Shift). Home and End, Cmd+Left and Cmd+Right are the ends of a row; Cmd+Up and Cmd+Down, Ctrl+Home and Ctrl+End the ends of the text. Left, Right and the editing keys stay with the text system. Pass the key event of the focused textarea to it, then the result to TextareaLayout.Move, then the new offset to the editor.
