eclipse Luna: command “Debug Last Launched” missing (?)

Question

Does anyone know what happened to 'Debug last launched' -- using eclipse Luna ( M7 Release - 4.4.0M7 ) on KUbuntu and the command seems to be missing.

There's 'Debug as', or by using the mouse and menu dropdown I can get the functional equivalent, but as I'm debugging, there's no command option to bind a keyboard shortcut to that I can find (such as F11).

eg same functionality as in: http://help.eclipse.org/indigo/index.jsp?topic=%2Forg.eclipse.jdt.doc.user%2Freference%2Fmenus%2Frun%2Fref-dll_debug.htm

This one was confusing : thanks to "greg-449" for the answer

Turns out that the command "Debug last launched" is available only once you enable the preference change: Go to > "Run/Debug" -> "Launching", then see 'Launch Operation', and change it to "Always launch the previous launched application"

At that point, the command for "Debug last launched" will magically appear, and be your default.

This is especially confusing, since only by changing that preference, will the "Debug last launched" command be even available in the "Preferences==>General==>Keys" dialogue (what comes up when you hit 'Control + Shift + L' twice)
