list files in mtime order

Simple but useful; list files in the current directory in mtime order. Useful if you've been working on something and then take a day or two off.

access to last touched or created file with arrow_up_key immediately after displaying the file list

Display recursive file list (newest file displayed at the end) and be free to access last file in the list simply by pressing arrow_up_key i.e. open it with joe editor. BTW IMHO the list of files with newest files at the end is often more informative. Put this 'lsa' function somewhere in your .bashrc and issue $ . ~/.bashrc or $ source ~/.bashrc to have access to the 'lsa' command immediately. . (the function appends command "joe last_file_in_the_list" at the end of command history)
