10.3: Use spatial keyboard navigation in Exposť
Authored by: vindu on Dec 10, '03 12:09:10AM
There's a difficult mathematical problem related to this arrow-navigation feature, which Apple (understandably enough) have chosen not to solve. The problem is "What is a good rule for hopping between rectangular windows, so that evey window is accessible one way or another?"

Just for fun, I found a way of "breaking" arrow navigation. Set up five windows, resized appropriately, in the following configuration (hashes represent window regions, dots represent the background; apologies for the crudeness of this picture).

Now hit F10 and play with the arrow keys. You'll find (if you get the setup right) that there is no way of getting to the middle window -- if you try to, you simply end up cycling through the outer four windows. :-)

cheers, Vin

BY george you are right. I just put a Safari window in the upper left and the lower right... not operlapping and moved the small downloads window into the section left on the lower left. You can't get to the Downloads window.

Use the TAB key to jump to non-arrowable islands.
