Hi, 

I've added some additional code to this great hotkey so that, if a Google Search window is already open in a Chrome browser, it performs the look-up in this Google Search Chrome tab instead of launching a new Chrome tab each time you use the hotkey.

Best regards,

Lieven

!g::

chrome := "- Google Chrome"
found := "false"
tabSearch := "Google Search"
curWinNum := 0

SetTitleMatchMode, 2

OldClipboard:= Clipboard
Clipboard:= ""
Send, ^c ;copies selected text
ClipWait

WinGet, numOfChrome, Count, %chrome% ; Get the number of chrome windows
if(numOfChrome = 0){
Run http://www.google.com/search?q=%Clipboard%
}
else{
WinActivateBottom, %chrome% ; Activate the least recent window

WinWaitActive %chrome% ; Wait until the window is active

ControlFocus, Chrome_RenderWidgetHostHWND1 ; Set the focus to tab control

; Loop until all windows are tried, or until we find it
while (curWinNum < numOfChrome and found = "false") {
WinGetTitle, firstTabTitle, A ; The initial tab title
title := firstTabTitle
Loop
{
if(InStr(title, tabSearch)>0){
found := "true"
break
}
Send {Ctrl down}{Tab}{Ctrl up}
Sleep, 50
WinGetTitle, title, A ;get active window title
if(title = firstTabTitle){
break
}
}
if(found = "false"){
WinActivateBottom, %chrome%
curWinNum := curWinNum + 1
}
}
if(found = "true"){
Send, !d ;focuses on address bar
Send, %clipboard% ;pastes copied text
Send, {Enter}
}
if(found = "false"){
Run http://www.google.com/search?q=%Clipboard%
}
}
Sleep 200
Clipboard:= OldClipboard
return
