Writing AutoHotkey scripts for a series of IF queries

Hello,

What is the general format or syntax for writing a series of IF queries in AutoHotkey?

I'm very familiar with the syntax for doing the same thing in Excel. For example:

=
IF(CriteriaA,ActionA,
IF(CriteriaB,ActionB,
IF(CriteriaC,ActionC,
IF(CriteriaD,ActionD,
"`"))))

Select allOpen in new window

In the above formula, once a particular Criteria is found to be true, the corresponding Action is executed and the formula stops. If none of the Criteria are true, the formula sends a backtick ("`").

Note: I am a quadriplegic with paralyzed hands. As a result, I have AHK scripts written for almost every conceivable action and generally have several hundred of them, each with its own hotkey, running at the same time. That creates the problem of having and remembering a large number of hotkeys.

What I would like to do is, for a given Hotkey, set up multiple Actions with the Action being executed dependent on which window is active.

So for example, let's say the Hotkey is F2, the script would look something like this (I know the following is not a real script but hopefully it conveys what I am after):

F2::
SetTitleMatchMode, 2
IfWinActive, Excel
   {
   GoSub, ExecuteActionsA
   }
IfWinActive, PowerPoint
   {
   GoSub, ExecuteActionsB
   }
IfWinActive, Chrome
   {
   GoSub, ExecuteActionsC
   }
IfWinActive, RingCentral
   {
   GoSub, ExecuteActionsB
   }
Return

Select allOpen in new window

In this way, and assuming I can get a given Hotkey's script to stop once it finds the active window, I could have a single hotkey trigger multiple different macros depending simply on which window is currently active.

Thanks
