bind_key block form can not correct resolve pressing key.

[zw963]

e.g.

bind_key [KEY_LEFTCTRL, KEY_F] do |_ev, op|
  op.press_key [KEY_LEFTCTRL, KEY_L]
  op.release_key [KEY_LEFTCTRL, KEY_L]
end

it worked, But, when keep pressing CTRL-F, it is only move one char forward.
we must CTRL-F CTRL-F to move two char forward.

if not use block form, it worked.

bind_key [KEY_LEFTCTRL, KEY_F], [KEY_LEFTCTRL, KEY_L]

I don't know how pressing_key is used in this case, maybe this method
is for this situation?

Thanks.
