Key binding for Eclipse commands

I would like to bind the Toggle Breakpoint command, org.eclipse.debug.ui.commands.To开发者_StackOverflow中文版ggleBreakpoint, to F9 key.

I extended org.eclipse.ui.bindings in this way:

<extension point="org.eclipse.ui.bindings">
  <scheme
        description="Default scheme for xvr"
        id="org.xvr.scheme"
        name="xvr.scheme"
        parentId="org.eclipse.ui.defaultAcceleratorConfiguration">
  </scheme>
  <key
        commandId="org.eclipse.debug.ui.commands.ToggleBreakpoint"
        contextId="org.eclipse.ui.contexts.window"
        schemeId="org.xvr.scheme"
        sequence="F9">
  </key>

But when I launch my RCP application nothing happens if I press F9.

What am I doing wrong?

EDIT

Sorry for the misunderstanding, but I'm developing a new product from eclipse and I can't use the preference window of eclipse.

I have to provide a binding through org.eclipse.ui.bindings extension point.

EDIT2

Thanks to Paul, using tracing I saw that an exception is thrown when I press F9

COMMANDS >>> execute >>> starting: id=org.eclipse.debug.ui.commands.ToggleBreakpoint; event=ExecutionEvent(Command(org.eclipse.debug.ui.commands.ToggleBreakpoint,Toggle Breakpoint,
        Creates or removes a breakpoint,
        Category(org.eclipse.debug.ui.category.run,Run/Debug,Run/Debug command category,true),
        ,
        ,,true),{},Event {type=1 StyledText {} time=25349140 data=null x=0 y=0 width=0 height=0 detail=0},org.eclipse.core.expressions.EvaluationContext@ffa7e1)

You need to add the following to plugin.xml, where defaultHandler is a class extending AbstractHandler and overridding execute()

   <extension point="org.eclipse.ui.commands">
    <command name="Remove All Comments"
        defaultHandler="commentremover.actions.CommentRemover"
        description="Removes all comments in source code"
        categoryId="org.eclipse.jdt.ui.category.source"
        id="commentremover.removeallcomments">
   </command>
</extension>

Also, you need to add the following, where commandId equals the id of the command you defined above

    <extension point="org.eclipse.ui.bindings">
    <key sequence="Ctrl+Shift+D"
        commandId="commentremover.removeallcomments"
        schemeId="org.eclipse.ui.defaultAcceleratorConfiguration"
        contextId="org.eclipse.jdt.ui.javaEditorScope"/>
</extension>

The above is all I needed to get my plugin to work. You will know it is working if it appears in the "Keys" preference menu. It is a plugin that removes all comments in the source code when you press Ctrl+Shift+D.

I suggest you go to

Windows → Preferences → General → Keys

and simply assign F9 to the Toggle Breakpoint command.

You don't specify which platform you're working on, but...

one some platforms - e.g. MacOS - the key assignment for F9, F10, etc cannot be changed :-(

You can try that out inside a regular Eclipse as well from the Keys preference page.
