// copy_clipboard "primary"  // primary or system, default is system
// These keybindings mostly override everything about the default keybindings in an attempt
// to mimic the best parts of the Doom Emacs / Spacemacs keybindings style.
// 
// The keybindings are meant to be mnemonic as possible.
// 
// I'm referring to "panes" as "windows".
// For most of these modes I'm thinking of them as mnemonic key namespaces that take you to
// an action. For example, to move one pane to the left: `prefix` -> `w` -> `h`
// where `prefix` is the keybinding to get from "locked" mode into "normal" mode
// `w` takes you from "normal" mode into "pane" mode, then `h` moves panes and terminates the action.
// Once in "pane" mode ther are some non-terminating actions available, and I'm thinking of those as
// "transient" states that allow you to do a bunch of repeated actions in a row before exciting with `Esc`.
// I was introduced to this concept in Spacemacs.
// That's the overall strategy with these keybindings. This strategy is super easy to remember for me, and 
// does seem to reduce wrist strain (the dreaded RSI :scream:)
// it would be super cool to define custom modes, maybe i could make an attempt at that
// https://github.com/zellij-org/zellij/issues/248
