I should second what snoge00f said, if you're writing your own bind files to load manually try your best to use a "clean" editor that doesn't append formatting or style tags to the file on save. Notepad, Notepad++ or Notepad2 are perfect for this.
not sure why he chooses tray 7, i use tray 4 and 5 myself for 2 different key binds
tray 4 you can use with shift-1/0, tray 7 not.
So you can access 40 hot-keys (tray 1-4), if you use row 4 you have "only" 30.
