Look down at the last post. There is a solution that works. I just tried it and was able to type a shifted character. It’s a bit cumbersome to use, since it is a separate little window, but it does the trick.

Here is the solution I found at the above link:

“SOLUTION TO OSX ONSCREEN KEYBOARD STICKY KEYS!!!!
by John A. Collins – 1/12/10 8:09 PM In reply to: Another Solution by Colin Pye

Use Finder to navigate to the folder > System > Library > CoreServices > Menu Extras, and double click on the file ‘Ink.menu’. This will cause an Ink icon to appear on your menu bar. You can use the drop down menu to access Ink Preferences and turn Ink on. Also check the “Show Ink Window” check-box. This is a little window with modifier keys that stick once or lock down by double-clicking. Combine this with the regular onscreen keyboard and you have a mouse-only solution for all your text input needs. Why Apple failed to include sticky keys by default I will never forgive. Please, If anyone knows a good place to post this info where it will be most helpful, let me know or go ahead and do it.
PS this also works great if you want to use a touchscreen-only setup.”

Thanks for the Bamboo demo. Well done.

I have enjoyed reading the posts on your site. I’m not disabled nor do I know anyone who is. I find your posts very interesting.

The website is a very clean design and I like the style of your writing and your narrative voice. Keep up the good work.
