Many times, i use commands like
M-x what-face to get the font face for character under cursor, (or)
M-x find-function-on-key to get the key bindings for a key sequence. These functions work on the main frame/buffer.
But, how to get the properties for minibuffer's face font (or) may be, key bindings for key inputs (or)
copy-region on minibuffer itself?
