Modified Dvorak quick fix

Here is the question that is related.

Changes keyboard
    wget -qO- | sh
    wget -qO- | sh  
Temp Modified Dvorak w/o Pg&PgUp
    wget -qO- | xmodmap -
The rest of the following will require a restart.  The first changes Ubuntu default dvorak keyboard to modified dvorak 
    wget -qO- | sudo tee /usr/share/X11/xkb/symbols/us
The following will set the context key and right control key as Page Down and Page Up
    wget -qO- | sudo tee /usr/share/X11/xkb/symbols/pc
And lastly this sets the RAlt key to a Page Up key.  This shorcut doesn't work with the combination 
    wget -qO- | sudo tee /usr/share/X11/xkb/symbols/altwin

backup /usr/share/X11/xkb/symbols/us

Lastly you can download vr.ahk for windows here
OSX PCKeyboardHack,KeyRemap4MacBook,Karabiner is the only way to remap the PgDn & PgUp keys.  Here is my private.xml

    wget -qO- > /Library/Keyboard\ Layouts/DvorakModified.keylayout

Regular Karabiner is interesting
