Dear list members, This is small try using nautilus to simplify the navigation process on Desktop icon view.
*Issue:* Desktop is the very first screen after login to system. A visually impaired user may need to know what is available on the desktop by traversing it once. To visit all icons, generally the user starts with top icon of first column by pressing Home. Then he presses down arrow key to traverse all icons of current column. When he reaches the bottom, he either goes back to top icon, moves left to top icon in second column, then moves down to last icon in the column. Or he presses right arrow key to move to bottom icon of second column, then moves up to top icon of the column. Proceed to next column if any and stop when the last icon is reached. For a sighted user it is easy to select the correct arrow key to move on to next column/item. But in absence of visual feedback it is very confusing with item repetitions, and with different arrow key directions. There should be an easy way to navigate through icons on desktop for traversing or searching. The* solution patch* (bug: 613111) helps user to traverse the desktop icon view completely using a single arrow key (Down arrow key). When focus comes on last item of a column, navigation automatically moves to the topmost item of next column. Thus user is able to traverse from first item to last item without missing any. And user need not use different arrow keys (left/right/up arrow key) to move on next column/item. *Important assumption:* solutions works well with setting “Clean Up items by name” on desktop icon view.
