| 8 Notes on CSS media types used: | |
| 9 | |
| 10 1) projection -> slideshow mode (display one slide at-a-time; hide all others) | |
| 11 2) screen -> outline mode (display all slides-at-once on screen) | |
| 12 3) print -> print (and print preview) | |
| 13 | |
| 14 Note: toggle between projection/screen (that is, slideshow/outline) mode using t-key | |
