Live TV Tuner: HDHomerun
Operating System: Windows 10
Browser: MS Edge
Function: Live TV
When watching live TV, especially when you want to watch two football games in a back and forth manner, having a recall button to the previously watched live TV channel. This button should be mappable to a specific keyboard key. I prefer the spacebar but that would pause the live channel rather than recall. Windows Media Center used the spacebar and made for an easy and quick user experience.
