Returns a table holding the effective default set of key_tables. That is the set of keys that is used as a base if there was no configuration file.

This is useful in cases where you want to override a key table assignment without replacing the entire set of key tables.

This example shows how to add a key assignment for Backspace to copy_mode, without having to manually specify the entire key table:

local wezterm = require 'wezterm'
local act = wezterm.action

local copy_mode = nil
if wezterm.gui then
  copy_mode = wezterm.gui.default_key_tables().copy_mode
    { key = 'Backspace', mods = 'NONE', action = act.CopyMode 'MoveLeft' }

return {
  key_tables = {
    copy_mode = copy_mode,
