Eclipse double click scope selection and Alt+shift+up not working after installing aptana plugin

Question

Double click for scope selection and Alt + Shift + ↑ were working fine before installing Aptana Studio plugin, but now both are not working. Is there any setting to enable it again? I'm using Eclipse Kepler Service Release 1

Answer 1

There may be key conflicts occurred between original short-cuts and with the Aptana plugins.

Go to Window->Preferences. Type keys in the search box. Type Shift+Alt+Up in the keys preference page search box. If there are multiple commands registered then check the context of all these commands or assign new short-cut key.

!How to do this!

As you see in the picture. For Alt+Shift+Up keyboard short-cut multiple commands are registered. Change these short-cuts and make them unique.Click on Binding text box, delete the content and Hold your Ctrl key and Press 0.

Make sure that this short cut is not assigned to any other commands. Now you can do selection scoping using the new short-cut i.e Ctrl+0 while editing java source.
