Хорошо.

Control,ExStyle,-0x4,,ahk_id %CtrlHWND%

Хотя, нет, не работает...

Надо в опции элемента добавлять "r1"

Как-то так?

Gui, 2:Add, Edit, r1 w120 hwndhmodkey1 gWriteIni, % Hotkey_HKToStr(modkey1)

; K - Определять клавиши клавиатуры
; M - Кнопки мыши без левой и правой.
; L - Левая кнопка мыши, определяется только при удерживаемой правой кнопке мыши.
; R - Правая кнопка мыши.
; J - Кнопки джойстика, определяются только без модификаторов.
; D - Определять левые и правые модификаторы.
; S - Определять только одну нажатую клавишу, то есть без комбинации с модификаторами. С этим параметром опция "D" не имеет смысла.

Возникла необходимость задавать кнопки модификаторы (Shift...) в качестве одиночного хоткея, но это не получается, т.к. требуется ввод обычной кнопки.
