SplitVertical

Since: 20201031-154415-9614e117

Splits the current pane in half vertically such that the current pane becomes the top half and the new bottom half spawns a new command.

local wezterm = require 'wezterm';

return {
  keys = {
    -- This will create a new split and run your default program inside it
    {key="\"", mods="CTRL|SHIFT|ALT",
      action=wezterm.action{SplitVertical={domain="CurrentPaneDomain"}}},
  }
}

SplitVertical requires a SpawnCommand parameter to specify what should be spawned into the new split.

local wezterm = require 'wezterm';

return {
  keys = {
    -- This will create a new split and run the `top` program inside it
    {key="\"", mods="CTRL|SHIFT|ALT", action=wezterm.action{SplitVertical={
      args={"top"}
    }}},
  }
}
