I don't mean to be all "BuT iT's cLOseD SoURce" but you should give Logseq or Zettlr a try. They're similar WYSIWYG markdown editors, but also FOSS. Zettlr also has vim keys.
I've been using linux pretty exclusively at home for almost 25 years now. Program. Script. Work in the shell a lot, and the other day I had to use vim and it took me a while to remember the basic commands. I'm a nano guy :\
A lot of my personal dislike for VIM would be done away with if it just had a helpful common keys cheat sheet (basic cursor navigation, edit mode, exit with and without saving, etc) at the bottom of the editor window like Nano does.
I just remembered that Bram Moolenaar, the author of vim has recently died...
He was a real good person. Back when he released his first vim for Amiga Computers I exchanged some emails with him and he handled even my less smart suggestions very professional.
I just take the chance to remind everyone to spend some money for his Uganda Charity.
I just noticed someone should try xkill if they get the chance. If that doesn't work they should rephrase the question. That is all. This will be my last grand contribution for today. Have a nice Wednesday everyone :3
Great idea for when you start in IT! Always had trouble first year in my apprenticeship when i had accidentally opened vim.
Ask for first time and after 2 months not used.
