Unable to set port for proxy chain using just the keyboard

When I am using zap with a screenreader (JAWS), and I want to set a proxy chain, I can
set the host, but when I tab to the port field, I am unable to set it using the keyboard.
 I have tried using the arrow keys to scroll down to port 80, but that takes forever,
and when I click ok, the value is not saved.

This field should be combobox so that the user can either scroll to the desired port,
or simply enter it.  Also the setting should be saved when the ok button is clicked.2.3.1
on windows 7 64-bit using jdk 1.7.0_67reproduce the problem?

Start by reproducing the proxy-chain port-field problem with keyboard navigation and a screenreader on the described Windows and JDK setup. The work is done when the port can be entered or selected without prolonged scrolling and the chosen value remains saved after clicking OK.
