You can do this without changing location of code explorer. For this you need two steps: Step 1. After pressing Alt+L focus is set to tool panel in left (e.g. to file explorer). Step 2. After pressing Tab key focus is set to code explorer.
You can write script which executes both steps with one shortcut. -- <http://forum.pspad.com/read.php?2,35485,35514> PSPad freeware editor http://www.pspad.com
