Eclipse CDT and NSight Eclipse Edition both do not have a default keyboard shortcut for Build Project. They do have
Ctrl + B for Build All, which builds all the projects in the Workspace. This is a surprising omission considering how frequently Build Project needs to be used by a C++ or CUDA developer.
You can assign a new keyboard shortcut for Build Project, by going to Window > Preferences > General > Keys. On my computers, I just remove the
Ctrl + B shortcut for Build All and assign it to Build Project.
Tried with: Eclipse 3.7.2, Eclipse CDT 8.0.2 and Ubuntu 12.04 LTS
