Commands are the preferred way of doing this. However in my case they are
inappropriate since they must be defined in the plugin manifest whereas my
actions are calculated dynamically once the plugin is already running in
the RCP app. Therefore I would like to use the old method of setting
IAction.setAccelerator(SWT.CTRL | 'S') for example. Although this
displays the accelerator key next to the action label (CTRL + S) the
accelerator has no effect. What am I doing wrong and how do I get this
working?
Thanks.

Wei,
Thanks for your response. I'm not sure this is the problem since I have
tried accelerators that do not have any equivalent bindings in the
workspace (e.g. ALT + 'B'). Any further suggestions?
Also, does anyone know if it is possible to uninstall those actions that I
don't require such as Save (or prevent their installation in the first
place), these have no meaning in my RCP application? Which plugin
installs these?
