## SpawnCommandInNewTab

Spawn a new tab into the current window.
The argument is a `SpawnCommand` struct that is discussed in more
detail in the [SpawnCommand](../SpawnCommand.md) docs.

```lua
local wezterm = require 'wezterm'

return {
  keys = {
    -- CMD-y starts `top` in a new tab
    {
      key = 'y',
      mods = 'CMD',
      action = wezterm.action.SpawnCommandInNewTab {
        args = { 'top' },
      },
    },
  },
}
```
