Command-Tab Plus

If you're not satisfied with Mac's default toggle hotkey (⌘ + tab), try Command-Tab Plus, an enhanced application switching tool. With Command-Tab Plus, after calling the program to switch the window, you can activate the window by pressing the program's corresponding number in the window. Instead of the default switch hotkey, you can only press the tab key to switch. Command-Tab Plus also supports modifying the interface color, icon size, and user-defined shortcut keys (option + tab is the default)
