Subtitles size shortcuts

In history is written that increase/decrease of subtitles was added (with shortcuts). I can't find what keys are for controlling these options, using menu for this is very uncomfortable :?

no default keys are assigned to this.

open bsplayer's preferences, select the key definition and winlirc tab, scroll to the end of the key definition list
you'll see increase subtitle font size and decrease subtitle font size
set your favorite keys
