- * 1. Esc input mode.
- *    When ESC sequence is in the buffer and it doesn't match any known
- *    ESC sequence => ESC means TB_KEY_ESC.
- * 2. Alt input mode.
- *    When ESC sequence is in the buffer and it doesn't match any known
- *    sequence => ESC enables TB_MOD_ALT modifier for the next keyboard event.

- * If 'mode' is TB_INPUT_CURRENT, it returns the current input mode.
