* line wrapping

* Fix magit invisible changes in terminal
* Deconflict Emacs and Kitty hotkeys
* if nix in path, prefer nix versions of emacs packages
don't use :straight t in use-package declarations
instead, have section that conditionally runs straight-use-package directives if necessary

** questions
*** Why does xy copy the newline but x;y doesn't?
*** Beacon mode
How does beacon mode decide whether a movement creates all possible cursors or just one?
How to express "insert before the second word of the line"?
Why doesn't visit work consistently in beacon mode?
*** defining C-<something> keys in normal mode seems to fuck everything up for some reason
** sexp state
** notes
*** r replaces selection with yank buffer
* Notes from Mastering Emacs
** C-x # in emacsclient says "done with current buffer"
** C-x 8 RET (insert-char) for to insert weird characters
** C-h m (describe-mode)
** I in embark goes to manual
** (global-set-key [remap <A>] '<B>)
remaps all keybindings that refer to <A> to <B>
** repeat-mode
describe-repeat-maps to see which keys repeat
** tab-bar-mode
replacement for perspective.el
offers window configurations as tabs, similar to iTerm/Kitty
also look into tab history mode
** bookmarks
C-x r (m)ark, (l)ist, jump to (b)ookmark
** registers
C-x r (s)tore region, (i)nsert contents
C-x r (SPC) store point, (j)ump to register
