Good afternoon and thank you for posting on the Final Fantasy XIV Technical Support Forums.

It looks like we were able to replicate this issue on our side, but we couldn't find a way to make it work unfortunately. Due to this, we'd like you to submit a bug report in the following forum: http://forum.square-enix.com/ffxiv/f...2-In-Game-Bugs

Be sure to follow the steps in the sticky thread on that forum.

In the mean time, have you tried binding the second hotbar to something that doesn't need a modifier (such as F1-F12)? I know these are bound to something else with the default setup, but it may be worth finding some keys that you don't use and try binding the hotbar commands to those.

Additionally, can you elaborate on the disability you have? We may be able to find an alternative solution if we know more about your condition.

We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!
