AutoHotkey: Makedir and file create history

/*

This script allows you to use directories and files creation
history in the F7 and Shift-F4 dialogs respectively. History
depth is defined by the "depth" parameters under appropriate
sections in the ini-file created in the script dir.

Up/Down : scrolls history in the edit box.
Alt-Down: shows a drop-down history list under the edit box.

Note: works ONLY via keypressing!
