Is it possible to assign Home and End key function (moving focus to top (..) or bottom (last file/folder)) to other keys - preferably Left and Right arrow keys ?
Yes. Open the customize dialog (right click at the tool bar, "customize", then the "keys" tab), & make two new commands, using Select FIRST, & Select LAST as the commands. There you can choose the arrow keys as the trigger key. But keep in mind, that it breaks the functionality to move the horizontal scroll bar. But many mouses have a tilt function for the scrolling wheel, which does the same.
Thanks. As this solution is very slow and Select FIRST points to 1st file or folder, not the ".." item, im not gonna think about it further.
Oh, sorry, i thought yoe were talking about the first/last file. You could change the one command to following, of course.
Go ..
