Reading the help docs, I couldn't quite visualize what this "Leap" button was. There's no image (that I saw) of the Canon Cat keyboard on this site. Turns out the Leap keys are situated directly under the spacebar: https://www.theverge.com/2011/12/28/2665791/jeff-raskin-canon-cat-humane-ui https://www.theverge.com/2011/12/28/2665791/jeff-raskin-cano... For the way I type, with my thumb angled so the knuckle would hit the Leap key, that would be absolutely infuriating. But it's an interesting idea nonetheless. It also had a "Learn" key, which seems to have been used for constructing macros. Neat! The example they give for it is a find operation to replace "dog" with "cat". I think the vast majority of people who spend a lot of time in word processors today still don't know how to use macros, and part of that is an accessibility problem; what sub-menu (or sub-sub-menu) would that be hidden in? It's interesting to think of an alternate reality where users learned to create macros as part of using a computer. Maybe we'd have more coders if so.
