Eclipse Short Cut: File Search
ctrl + H opens the search dialogue box. Click on customize and check the option 'Remember last used page'. First time you have to select the tab file search and perform a search. After that if you press ctrl + H , it will automatically point to file search tab.
There is none, but if you go to Windows - Preferences - General - Keys, and type File search in the filter text box, you'll then be able to select the File search action, and type your own key binding.
You can change all shortcut keys in eclipse for instance:
Window -> Preferences -> General -> Keys -> search: File Search -> Binding -> *what ever key combination you like.
