I updated helpbrowser to use arrow keys for navigation, and updated the version to 0.2?
-took out searching the user libraries (only kept static path) because things were being added twice if people want to load a library on startup and it was in the staticpaths.
-added navigation by arrow keys
-changed method of destroying listboxes because of arrow navigation.
Each listbox is now named in the pattern: helpbrowser.frame.root(listbox#). Whenever focus changes to a listbox, or a listbox is created (to avoid name clashes), the list of children is searched in the check_destroy proc using this name pattern and deletes all listboxes 2 or more after the focused one. This was the best method I could come up with. When focus changes, the scroll_destroy proc scrolls the focused listbox to the left (because it was scrolling right for some reason even though the right arrow key is bound) and then calls check_destroy.
I also added new procs for each "type" of listbox for dealing with arrow key navigation
