My workaround for this was updating the shortcut key for code completion plugin. You can follow the steps to change CTRL + SPACE with your preferred value. Prior to these steps, please get a backup of your plugins folder under your squirrel installation path and proceed with your own risk! 1-)Install 7-zip or maybe another archive app like winrar might work. Not sure :) 2-)Close SQuirrel application. 3-)Open 7-Zip. Go to your installation folder by browsing in 7-Zip to find code complete plugin jar....
