Could you make the spacebar function as "enter" within menu's like the hatching-menu. This would speed up things a lot since spacebar is already used to repeat the same command. This is done so in autocad (please check it) and rises productivity.

ex. in autocad after having used the hatch command once, you can keep on doing different seperate hatches, by pressing spacebar over and over without having to click once with the mouse on distracting buttons within the menu.

Using the program this way i what sets it' apart from competing Vectorworks and or 2D-capable software.
