QuickDialog provides keybinding for selecting options in the dialog window. It currently allows binding of the first option to 1 or F, and will allow binding of the first option to any key in the near future.
Default bindings - Dialog options are bound by default to hotkeys 1-9 and numbers 1-9 on the number pad.
Custom first-option binding - You can toggle between the hotkey binding for the first option by typing /qd.
/qd - Toggles between 1 and F as the hotkey for choosing the first option.
