Sorry to be the bearer of bad tidings, but the keyboard shortcuts are not user-definable. All I know about the space bar removal is that it is a key very much used by some accessibility tools. If you wish, you could look in the suggestion forum and see if there is a suggestion to create user-definable keys. I know I'd like to be able to assign keystrokes to macros. :) For what it's worth, the keystroke to set a waypoint is simply "q". Other command options can be found here .
