# Slides

*(Just a very rough attempt to provide some organization.)*

Below is a listing of all the slides that I don't mind making available for public consumption, in reverse chronological order. They come in a variety of different formats (Google slides, HTML slides, hand-written notes, or PDF slides made using LaTeX), depending a bit on my mood and when I prepared them.

This site is a bit sparse now because mid 2021 I decided to switch from my patchwork Reveal.JS template to using the cleaner and more light-weight Shower for my HTML slides. My old Reveal.JS slides used Reveal-Hugo and was written in MarkDown. Rather than trying to retype everything in HTML, I just dumped those slides. In time this should be repopulated.

There is a search box with a very rudimentary search function (exact phrase matching only). Use the check-boxes to filter the talks by type.

### Navigation of HTML slides

I modified the navigation keys a bit from the original Shower; I also added swipe navigation.

- Keyboard:
- In list mode: arrows to select slide, Ctrl-Enter to open slide, Ctrl-Shift-Enter to start slide show from beginning.
- In presentation mode: down/right/n/j/Enter/Space for next slide, up/left/p/k/Shift-Enter/Shift-Space for previous slide, Esc to return to list mode.

- Swipe (only for presentation mode): two-finger swipe down/right for previous slide, and two-finger swipe up/left for next slide.
*(Two finger swipes are used so as to allow annotations during presentations using styluses.)* - Mouse navigation is unfortunately currently not supported by Shower. As a work around: select the slide you wish to view in list mode. Use the browser's "back button" to return to list mode when you are done, and select the next slide you wish to view.
