[Share] Set different keys dynamically base the process name, e.g. you are open a editor within the wezterm.

I am newbie to lua, following code seem like work for me, any improvement is welcome!

we assume the editor process name is dte

config.key = {
---   ...
}

key_index = #config.keys

wezterm.on(
  'update-right-status',
  function(window, pane)
    local info = pane:get_foreground_process_info()

    if info.name ~= 'dte' then
      new_key = { key = 'w', mods = 'ALT', action = act.CopyTo 'Clipboard' }
      last_key = config.keys[key_index+1]

      if last_key ~= nil and last_key.key == 'w' and last_key.mods == 'ALT' then
        return
      end

      table.insert(config.keys, new_key)
    end
  end
)

Above code work like this:

1. if dte is not opened, Alt + W will run wezterm action act.CopyTo 'Clipboard'
2. if dte is opened, above binding from wezterm isn't exists, so, it will use my dte editor config, copy -bi, which copy the content of selection into system clipboard (utilize OSC52 feature support by wezterm) and internal clipboard.

The above solution not work for some special action which activate a mode, e.g. search.

A more better(and performance) way to do this, check #4930 (comment)
