Live TV: up/down buttons to bring up mini guide

Hi all,

I have just got Kodi v17.1 running next PVR with my HDhomerun. Its working well!

During live TV is there a way to remap the up/down keys on my remote to bring up the mini TV guide.

At the moment when I press the up / down keys it will just bring up the OSD and I will then need to select the mini guide.

Any advice would be great.

Thanks
