" Keymaps
" =============================================================================
" Usually we're going to follow some conventions:
"   - If a command opens a new pane/buffer, we're going to give it a PRIMARY,
"     and that PRIMARY can be repeated or added a MODIFIER.
"
"     Our MODIFIERS are always the same:
"       * `s` for opening in a vertical split
"       * `S` for opening in a horizontal split
"       * `t` for opening in a new tab
"
"     Our PRIMARIES are defined in a command by command basis.
