See this I understand, why I press the shortcut key to save time, sometimes will special card. The CTRL key may be triggered when the shortcut key is saved ctrl+s this time. My above settings to html,jsp in the JS code to press the CTRL key link canceled, in fact, this function I feel very good, sometimes need code tracking when you use the CTRL key to link to other code. Especially in Java, this is not canceled. Fix it. The version of Eclipse is getting stuck.
