Bug 112106 [KeyBindings] Changed shortcut keys don't take effect
I have just changed the shortcut key mapping for a few commands, but they don't all seem to take effect. For example, I just mapped Source > Format to F11, and it shows up that way in Window > Preferences > General > Keys as well as in Help > Key Assist, but the F11 key doesn't format, and the shortcut key displayed in the Source menu is still Ctrl+Shift+F. I mapped Incremental Reverse Find to Ctrl+Shift+F and still have the same problem. I think the whole key mapping part of Eclipse needs to be redesigned, as it is difficult to use and doesn't even seem to work. It's very frustrating.

final Collection suffixes = expandParameters(startIndex + 1, parameters);
		if (suffixes.isEmpty()) {

				final Parameterization parameterization = (Parameterization) parameterizations
						.get(i);
				final List combination = new ArrayList(1);
				combination.add(parameterization);
				parameterizations.set(i, combination);
			}
			return parameterizations;
		}
		final Collection returnValue = new ArrayList();
		final Iterator suffixItr = suffixes.iterator();
		while (suffixItr.hasNext()) {
			final List combination = (List) suffixItr.next();
			final int combinationSize = combination.size();
			for (int i = 0; i < parameterizationCount; i++) {
				final Parameterization parameterization = (Parameterization) parameterizations
						.get(i);
				final List newCombination = new ArrayList(combinationSize + 1);
				newCombination.add(parameterization);
				newCombination.addAll(combination);
				returnValue.add(newCombination);
			}
		}
		return returnValue;
