New feature request - Keyboard dropdown opening

Good evening, I have Chronoforms 8.0.34 installed.

When you fill up a form, it's faster to use just the keyboard. Now you can skip from field to field using the "Tab" key, but if you have a dropdown I can't find a key to open and select the item of interest. In other forms I saw in Internet you can do this by the arrow down key, or by the space bar, but Chronoforms 8 doesn't seem to have this possibility (for now).

Thank you.
