I have my system set up a certain way. To change desktops, I use [CMD]+Arrow.
When I do this, it fools Minecraft into thinking that the [Control] key is held down in chat. Every backspace or chat navigation is then done word+by+word until the application is fullscreened.

Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
I can confirm this. Most mac users have this setup, as it gives more workspace - until I read this report, I was unsure what had caused this, thought it was just a 'standard' Mac bug from the start.
