AutoHotKey – How to Quickly Find an Open Window by Title

^+i::
if WinExist("ahk_class Chrome_WindowImpl_0")
  {
  WinActivate
  ControlFocus, Chrome_AutocompleteEditView1
  }
else
  Run "C:\Users\vleeshue\AppData\Local\Google\Chrome\Application\chrome.exe"
return

Should do the trick

("Chrome_AutocompleteEditView1" is the name of the omnibar control, so you could add Send ^a to select all)

Note: To get the ahk_class for your version of Chrome, e.g., ahk_class Chrome_WindowImp1-0, use the AU3_Spy.exe inside the autohotkey directory. This will allow you to find the correct ahk class for your chrome browser if the example one doesn't work.

Update: I can't reproduce, maybe it will be better with another control... To have a list of a window controls I use this code:

#Persistent
SetTimer, WatchCursor, 100
return

WatchCursor:
  MouseGetPos, , , id, control
  WinGetTitle, title, ahk_id %id%
  WinGetClass, class, ahk_id %id%
  WinGet, ControlList, ControlList, A
  ToolTip, Under Cursor:`nahk_id: %id%`nahk_class: %class%`nTitle:%title%`nControl: %control%`n`nWindow Control List:`n%ControlList%
return

So the controls of my google chrome 4.0.249.78 beta (36714) are:

• ViewsTextfieldEdit1
• Chrome_RenderWidgetHostWND1
• Chrome_AutocompleteEditView1
• Chrome_WindowImpl_01
• Chrome_WindowImpl_02

Russell's answer gets you a large chunk of the way there using RDP as an example. It's a little harder to detect that you're in vsphere/vmware console but can be done with the below. I've commented the changes/additions

#UseHook
#SingleInstance force

; A window's title can contain WinTitle anywhere inside it to be a match
SetTitleMatchMode, 2

setTimer, windowWatch, 500

windowWatch:
  ; if rdp OR (partial title matching vsphere AND you are in the console captured section)
  if WinActive("ahk_class TscShellContainerClass") or (WinActive(" - vSphere Client") and Control("MKSEmbedded1")) {
    if (!active) {
      active := true
      Sleep 50
      suspend off
    }
  } else {
    active := false
    suspend on
  }
return

; return ClassNN of mouse position
Control(ClassNN) { 
    MouseGetPos,,,,control 
    return (ClassNN = control) 
}

I use this to allow play/pause media keys to work in both rdp/vsphere

Media_Play_Pause::
  Sleep 50
  Run "C:\Foobar2000\foobar2000.exe" /playpause
return
