## 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 window { key = 'y', mods = 'CMD', action = wezterm.action.SpawnCommandInNewTab { args = { 'top' }, }, }, }, } ```
