[README] New default keybindings [second attempt]

[Christopher Roy Bratusek <zanghar freenet de>]

Hi all,

been reading your comments, and here is a trimmed-down proposed list:

Window Keymap

M-F4  -> Delete window safely
M-C-s -> Toggle Window Shaded
M-C-m -> Maximize Window Toggle
M-C-i -> Iconify Window

Decide :

A)

M-C-r -> Raise Window
M-C-l -> Lower Window

B)

M-C-r -> Raise or Lower Window

Global Keymap

M-C-d -> Show Desktop
M-C-e -> Display Errors
