I need to write a script to make the active window always on top, but all the examples are for AutoHotKey v1. How can I do this with AHK v2?

Use this (Hotkey is CTRL + SPACE):

^space::
{ WinSetAlwaysOnTop -1, "A"
}

How it works:

This script uses the WinSetAlwaysOnTop method to accomplish its goal. It takes several parameters, but not all of them are mandatory. -1 tells the function to toggle the setting to the opposite of whatever it was (e.g. OFF --> ON), and "A" tells it to use the currently active window (whichever window has focus). You can also pass it the name of a specific window, like "Calculator".

Here are some links to the relevant documentation:

• WinSetAlwaysOnTop
• WinTitle

Modified some AHK v1 code to alter the window title when a window's "OnTop" status is changed

!t:: { ; ALT + t
Title_When_On_Top := "! " ; change title "! " as required
t := WinGetTitle("A")
ExStyle := WinGetExStyle(t)
if (ExStyle & 0x8) { ; 0x8 is WS_EX_TOPMOST WinSetAlwaysOnTop 0, t ; Turn OFF and remove Title_When_On_Top WinSetTitle (RegexReplace(t, Title_When_On_Top)), "A"
} else { WinSetAlwaysOnTop 1, t ; Turn ON and add Title_When_On_Top WinSetTitle Title_When_On_Top . t, t }
}

Original code is thanks to Linear Spoon
