vim notes

Vim settings and notes.

1. Swapping Esc with Caps
   • Mac OS Karabiner-Elements (pqrs.org)
2. Key bindings I use
   1. cw to change current word in insert mode
   2. jk move cursor to end of line in insert mode
   3. kj move cursor to beginning of line in insert mode
   4. K == C in normal mode
   5. swap gj/j and gk/k in normal mode
   6. swap v and ctr-v in normal mode
   7. ctr-y yank to system clipboard (though I am hating this setting in obsidian now)
