How about add OpenDesktopManager feature.

[lokielse]

default key is win+tab.
I'd like to customize it.

You can already customize it!:)

Step 1

Decide what will be your new hotkeys. For this example, let's use Ctrl + Space, which will trigger Win + Tab

Step 2

Find the commands (symbols) for each of the buttons. For example:

Button	Command
Ctrl	^
Space	space
Win	#
Tab	tab

You can find the table for all of the buttons here.

Step 3

Edit the file user_config.ahk and add this line at the bottom of the file:

^space::send, #{tab}

Click here for explanation.

You make the program do a command with your selected hotkeys like this:

HOTKEYS::COMMAND

In our case we want the program to click some buttons (Win+Tab) when we press the hotkeys. The way to do this is to use the command send (comma is optional):

HOTKEYS::send, BUTTONS

If we want that pressing Ctrl + Space would press the buttons h e l l o, then we use this line

^space::send, hello

If we want it to automatically press a button other than a letter, then we use { } around it (For example tab should be {tab}).

In this example Ctrl + Space will press the buttons Win + Tab:

^space::send, #{tab}

You can read more about how it works here

Step 4

Start the program.

If it is already running, you can click the tray icon with the right button and select Reload.

(EDIT: Fixed the errors and formatting)

@Elijas Thanks for your detail guide.

// This one is work, but it is not my wanted.
^`::!tab

// This is what I want, but it dose not work.
^`::#tab

Oops, it seems that I gave the wrong solution. I've just got to my computer and fixed it. Try this:

^space::send, #{tab}

I've updated the comment above and explained this in more detail, too!
