One other thing that might be worth mentioning - if you use the keyboard a lot for entering coordinates or values, you can usually just type the value you want in immediately without having to click.

Like for instance if you are drawing a circle and you want to enter a radius of 5, you can just type 5 and hit enter, you don't have to click on the "Radius" entry box first.

When you type in a numeric key, MoI will automatically shift focus to either the first numeric input in the options panel, or if there are none there to the x/y/z control in the bottom panel.

Another example - if you want to enter a bunch of coordinates for a polyline, you can just type them in without clicking on the x/y/z control for each one if you don't want.
