im really new to emacs. using doom emacs. i need some help customizing a couple things for the first time.

so emac's default for moving to beginning/end of line is `C-a` and `C-e`. and emac's default for skipping to previous/next word is `C-left` and `C-right`. i want `C-left` and `C-right` to move to beginning of line and end of line. i also want `Shift-left` and `Shift-right` to skip to previous/next word (so same thing as default `C-left/right`)

also im using evil so `o` in normal mode will create and go to next line, and enter insert mode. i want to remap this to `c`. in vim this would be `nnoremap c o`.

how i can do this?

thanks
