Tab key doesn't complete commands in Run dialog

Question

I like to use the Tab key to complete or skip commands and links in shells and browsers when I am typing, but when I hit the Tab key in the Run dialog, it causes focus to leave the text box, so I'm forced to leave the home keys to use the arrow keys.

Is there a way change this behavior?

Edit: I found here a flag that enables autocomplete in the Run dialog. This doesn't solve the problem, but it helps when the command you want is the first option listed, because you just press Enter instead of moving to arrow key and selecting the command. In my case this solves about 90% of cases.

This registry setting should do it... it's always been a pain to find for me as well.

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\AutoComplete]
"Always Use Tab"=dword:00000001
