Open autocompletion tooltip with shortcut

[kuuup]

Hi 😃

Please provide a shortcut to open autocompletion tooltip (maybe ctrl+space).

• Autocompletion for objects opens after you type a dot and the first letter of a property or method. But it won't help you if don't know property names.

• When the tooltip closes because you changed cursor position you have to type the next letter to open it again.
