Cycle Frequently used fonts in Libre Office Writer 4.1.3

Hello everyone,
I use Libre Office writer for making and typing my documents and I love it. Only problem I face is that there is no simple easy way to cycle through frequently used fonts in my documents. I need to know shortcut of easy way that when I am typing in one fonts, I can change to other font without actually touching mouse. I want something like "Alt + TAB" we do to scroll through programs. I want something like that to scroll through fonts.

Please help.
