Issue title: Edit cell in Key Bindings window unviewable
 Issue body: In the key bindings windows, the right most "window" where the key binding parameters are edited is not viewable until you stretch the window past the resolution of a normal monitor. See attached photos. 

The only way I was able to view it was expanding window size to two monitors.

Issue found on my Windows 10 & Macbook Pro.
