One Powerpoint feature that Keynote does not yet have is animation triggers. In Powerpoint, you can set an animation to be triggered when a particular object elsewhere on the slide is clicked. This can be used to create interactivity for web-based elearning, or perhaps for presentations where there is some interaction from the audience and the exact sequence of clicks is not figured out in advance.
A workaround to create a trigger effect is to make the triggers into hyperlinks that link to slides that look identical to the slide containing the trigger, but which contain the response animation. For each trigger, there will be a corresponding animation slide. The animations are set to begin "after transition" or in other words, right after the slide loads.
In the example shown here, the two round jewels serve as the triggers. Clicking either round jewel appears to trigger the corresponding square jewel's animation. What really happens, though, is that the presentation jumps to the slide containing the correct animation, which is triggered by that slide's loading.

I had a lot of trouble getting TinyMCE text editor to work consistently in Drupal 5.9, so when I installed Drupal 6 and was scanning through the available modules, I was very glad to see that the WYSIWYG editor module could function as a replacement.
Although the easy-to-use WYSIWYG editor is popular with our site's users, sometimes I find it gets in the way, and want to turn it off.

However after installing it, I found there was no way to turn it off on a case by case basis, because the "Disable rich-text" link was not working. The javascript error shown was "tinyMCE.getEditorId is not a function"
Some tips on the Drupal forums which led to the solution. First, I had not noticed that the current version of WYSIWYG editor is only compatible with version 2.1.x of TinyMCE. I had installed a later version. So I removed the later version and replaced it with the older one. When I looked at the readme.txt file that comes with the module, it indeed has a note that it is compatible with 2.1x, but of course I hadn't read it while installing!
Error: tinyMCE.getEditorId is not a function
Once the downgrade was in place, there was a NEW javascript error: "editorTemplate is undefined."
Another message on the drupal forums contained a patch which helped fix this issue.
Editor Base Path is being set incorrectly
Go into WYSIWYG-editor.module and patch it:
