Description

I am reading through HtDP/2e and find it annoying that pressing Cmd+W or Esc can't close the canvas windows that appears while using the animate from 2htdp/universe. Cmd+Q, of course, tries to close the whole DrRacket IDE. The only way it seems is to use the mouse pointer to press the red close button.

Contributor guide

Research direction
Investigate the key event handling for canvas windows in the 2htdp/universe library on OS X. Check how keyboard shortcuts (Cmd+W, Esc) are currently processed and why they fail to close the window. Look at the event queue and window manager interactions.
