Reconfigure Live TV button

Hello,
i have a Sony Vaio WMC remote that has a “Live TV” button. when i press this button it takes me to channel listing. i want it to actually go to Live TV channel. either the last channel that was playing or a preset channel. i have MCE Remote addon installed (Add-on:MCERemote (wiki))
Kodi has option to automatically go to last channel when started, so i’m assuming this could be possible? kind of a noob to this so any help is appreciated. i couldn’t figure out the command to put in MCE Remote Under the Live TV button, currently its default is ctrl-shift-t
