I installed IntelliCalc and I like it. Yet another thing that I don't
have to leave the IDE for :)
There's a small problem - the default control in focus seems to be the
number 9, and when I use the keyboard to do (for example) 2+2, when I
press Enter I see both = and the focused control (9) pressed.
Same happens when one uses the mouse to click on numbers and then Enter.
I think that Enter should cause only = rather than a focused key.
