I was wondering does anyone know how I can use my right hand cmd button as a shortcut key for move focus to the dock. Someone did it for me, but I cannot seem to do it by going through system preferences and to keyboard shortcuts.
well do you mean magnify the dock, because if you just want to magnify it.
Go to the system preferences, then go to the one saying dock right there you can control all of the settings including magnification, size, and where on the screen you want the dock and other settings all about the dock.
In the Keyboard Shortcuts there is a "Move focus to the Dock" option that you can change to whatever key combo you want. Just make sure it's not a combo used by another system option or program. By default it should be set to Control+F3.
