I've just switched from xfce4-terminal to rxvt-unicode and I've been reading a lot of .Xresources and .Xdefaults files, piecing things together to create my own. My googling skills have left me with a number of unanswered questions; one of which is:Is there a difference between URxvt.font and URxvt*font?I have seen a number of variations, for example, the answer for this questions uses a asterisk in one line and periods in another.URxvt*scrollBar:falseURxvt*scrollBar_right: falseURxvt.keysym.Shift-Up: command:\033]720;1\007URxvt.keysym.Shift-Down: command:\033]721;1\007`Does that mean it doesn't matter or that it matters for some setting and not others? I'm hoping understanding the differences, if there are any, will help with the settings I can't get to work. 
Xresources / Xdefaults: Period or Asterisk?
