I do used IntelliJ IDEA as my development environment at past and I have recently started to use MyEclipse.
In IntelliJ, using the Ctrl+U shortcut on override/implement method go to original method in super class.
Does MyEclipse have similar shortcut and if it does how do I use it?
Assuming MyEclipse has the same menu command as standard Eclipse, the equivalent command is Open Super Implementation on the Navigate menu. It doesn't have a keyboard shortcut assigned by default, but you can add one.
