Keybind to toggle usage based CPU display

[cooperuser]

Describe the feature request

From the README:

 -u, --current_usage                        Sets process CPU% to be based on current CPU%.

It would be great if there was a way to toggle this mode from within the application. I find myself needing to switch back and forth during runtime and it would be really nice to be able to do so without losing all the graph data.

Possibly u for usage?

I plan on building an in-app config screen that would let you toggle options currently in the flags/config file, which should hopefully cover your use case as well?

[cooperuser]

Yes that makes it easier, though having a quick keybind for it would be nice too, similar to the % mapping for toggling showing percents vs raw bytes

[ClementTsang]

Gotcha, I'll consider that as well.
