about remote desktop problem

[Amaury VH]

I'm using ubuntu 12.04.1, and I change the shortcuts for the keyboard, 
for example "win key + D" to minimize all windows, "win key + E" to open 
nautilus.
When I try to conect to a machine with windows operating system using 
rdesktop command or remmina, the shortcuts in windows are the same to I 
use in ubuntu, just without the "win" key, for example, when I press 
"E", open a windows explorer, when I press "D" minimize all my open 
windows, how I can solve this problem?.
¿any solution?.
Apologize me for my language, I don't speak english.
Regards, Amaury.
