I gave up.
Calva ftw

Thanks to aculich for his configs. It's very difficult to find any sane configurations in the Emacs world.

• Comment/uncomment line/REGION with C-/ (I think I will be slowly heading towards VSCode controls...)
• Text manipulation around sentences is useless for programming -> change definition of a sentence to one revolving around parens
• which-func doesn't really work well
• C-BACKSPACE deletes too much; just stop at the beginning of the line, please

• Marking a region and pressing Backspace should delete it
• Paredit is trying to be too smart and doesn't allow to delete unmatched left paren, when it was left there by accident.
• Copy and pasting in Emacs is completely backwards; 'yank' is used in wrong context and it bothers no-one?
• S-DEL for deleting whole line

• C-<left/right-arrow> moves always too far; it should stop before brackets and line beginnings
  I'll stick to slurping and barfing with those keys
• Moving sexps around with C-<arrows> is a terrible, terrible idea for my muscle memory -> just move word by word
• Vim's % to move to a closing paren (solution)

• C-z -> absoulte winner
• C-k -> recenter-top-bottom
