** Font Size
|
||||
This was taken from [[http://emacs.stackexchange.com/questions/7583/transiently-adjust-text-size-in-mode-line-and-minibuffer][here]]. It is primarily invoked from a hydra defined below. It would be cool if it got the default font size from whatever the default font was but it does not currently do that.
