When you enable the double key shortcut (cmd + cmd), it doesn't work the first time after you have switched to a new application. Here is how to reproduce it:
Start 2 other applications (Chrome and iCal)
Start TotalTerminal and enable double key shortcut
Switch to first application (Chrome)
Hit double key shortcut
Close TotalTerminal
Switch to second application (iCal)
Hit double key shortcut
Hit double key shortcut again
Depending on how you do it, TotalTerminal won't open the first time you use the double key shortcut but will open the second time.
