I last raised this issue in Dec 2009, but I still haven't heard or discovered anything. Are there (or has anyone found) keystrokes to change the font or display size without going to the drop down menu (alt+ -)? In Libronix, I could increase/decrease the font/display size in a window as quickly as I could click ctrl+shift+< of ctrl+shift+>. I loved this feature and made constant use of it, especially when displaying texts on a projector screen.
Even when trying to change the font size via the drop down menu, I have to use the mouse to adjust the font size. I cannot find a keystroke that will allow me to move the slider once I have selected the font sizing bar.
