Another important item I left out of this list. Including motor
challenges the ability to use both hands does not exist... so
shortcut keys with a combination of two keys or more is not really very
viable. Yes I know there are sticky keys, however then the attn span and
frustration levels are a considerable issue.

Also the recall of such key combinations might be rather inconsistent.

I myself, working in so many software programs and browsers, cannot
recall all the keyboard shortcuts or many of them. So someone with some
comprehension or learning difficulties might be at a stronger
disadvantage.

Short cut keys do not work for everyone. Even if they are designed well.
