Finally got a few things sorted. Konsole starts oh-my-fish, which starts tmux. Learning basic tmux commands is good. Then use Kakoune in place of vim for basic editing. Need to brush up on all command options. Also, love it that oh-my-fish has a theme named after Isao Tomita! https://www.japantimes.co.jp/culture/2016/05/08/music/isao-tomita-japanese-pioneer-of-synthesizer-music-dies-at-84/
