In lfm/curses I can adjust the keybindings for all functions easyly using a
'keytable':
keytable = {
# movement
ord('p'): 'cursor_up',
ord('k'): 'cursor_up',
ord('K'): 'cursor_up2',
ord('P'): 'cursor_up',
curses.KEY_UP: 'cursor_up',
ord('n'): 'cursor_down',
ord('j'): 'cursor_down',
ord('J'): 'cursor_down2',
ord('N'): 'cursor_down',
curses.KEY_DOWN: 'cursor_down',
curses.KEY_PPAGE: 'page_previous',
curses.KEY_BACKSPACE: 'page_previous',
# misc
ord('#'): 'show_size',
ord('s'): 'sort',
ord('i'): 'file_info',
ord('I'): 'file_info',
ord('@'): 'action_on_file',
0xF1: 'special_regards', # special regards
ord('/'): 'find_grep',
ord('T'): 'touch_file',
ord('L'): 'create_link',
0x0C: 'edit_link', # Ctrl-L
0x0F: 'open_shell', # Ctrl-O
...
So it is not only for the directories, rather for every function in lfm and it
would be nice to use such a keytable when using urwid too. As you can see using
'j' and 'k' are just alternatives for the 'up' and 'down' keys, but for a fast
navigation much better (the same counts for 'page_up|down' ...).
Thanks for your help!
Greetings!
Fabian
