crtl+r(history search)
This one I didn't know this will be extremely helpful.
Ya it's nice, ctrl+a, ctrl+e, and ctrl+d are nice too so you can stay at "home" on the keyboard.

I don't use awk as much as I should, I essentially use it for a glorified csv reader haha

Ah, I never find CPU utilization to be something that I need to watch. Looks neat and impressive on the screen, but once I know the percentage of CPU, I don't care about seeing a chart, but I need to see load numbers, processes and memory stats.
