type wrongful character in the selection box

[ousmorez]

Describe the bug
While dropdown is closed, it opens after entering a key like (down arrow) but it prints "arrow Down" on the combo box. We should stop writing values that are more than one character on the select boxes or combo boxes.

To Reproduce
Steps to reproduce the behavior:

1. Go to Choicejs
2. Click on 'Right-to-left'
3. Select 'Choice1'
4. enter Arrow Down
   It will type it into the select box.

Expected behavior
We expect not to type anything in the select box.
