      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.

        "sudo !!", "tail -f", the unholy trinity that is "grep/awk/sed", and vim (all from within tmux).

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

                I honestly don't like htop very much. I prefer regular top. I find the output more useful.

                  htop works much better to see multi-CPU utilization though. Filtering is really nice too.

                    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.
