Buttons and not reacting to tab

Hi there, I'm working on a file explorer using cursive and I have a question. Can I make buttons not react (without disabling them) to a Tab events? That is, imagine file explorer ala Norton Commander and those two main panels, left and right and under them row of buttons, like remove del etc. I'd like the Tab event to only switch between left and right panel, but at the moment it goes to the buttons as well. Is this possible to not react to Tab events where buttons are concerned?
Thanks
