Using Functions Keys [1]

I have a unix app that accepts shift+F5 as one of its shortcuts. This key sequence works fine with putty and secureCrt. I could not get it to work with xshell. Hitting this key combo does nothing. I could not find anything in the option to customize or map keys.
Any ideas?

Thank you for your feedback. Shift + Function key combination is not available in current version. We will consider adding this feature in our future releases.

Please let us know if we can be of further assistance.
