of course you can, simply invoke your 'follow-key'whenever you swith a window.

Example: Lets say you use the following code for windowswitching:
Code:
<Hotkey F1>
   <ResizeAndPosition WoW1 WoW2 WoW3 WoW4 WoW5>
<Hotkey F2>
   <ResizeAndPosition WoW2 WoW1 WoW3 WoW4 WoW5>
<Hotkey F3>
   <ResizeAndPosition WoW3 WoW2 WoW1 WoW4 WoW5>
<Hotkey F4>
   <ResizeAndPosition WoW4 WoW2 WoW3 WoW1 WoW5>
<Hotkey F5>
   <ResizeAndPosition WoW5 WoW2 WoW3 WoW4 WoW1>
and you have bound your follow to 'f' then you could simply alter your code to:
Code:
<Hotkey F1>
   <ResizeAndPosition WoW1 WoW2 WoW3 WoW4 WoW5>
   <Sendlabel w1>
        <Key f>
<Hotkey F2>
   <ResizeAndPosition WoW2 WoW1 WoW3 WoW4 WoW5>   
   <Sendlabel w2>
        <Key f>
<Hotkey F3>
   <ResizeAndPosition WoW3 WoW2 WoW1 WoW4 WoW5>
   <Sendlabel w3>
        <Key f>

<Hotkey F4>
   <ResizeAndPosition WoW4 WoW2 WoW3 WoW1 WoW5>
   <Sendlabel w4>
        <Key f>

<Hotkey F5>
   <ResizeAndPosition WoW5 WoW2 WoW3 WoW4 WoW1>
   <Sendlabel w5>
        <Key f>
