Hi,
Is it possible to bind key sequence to one command in one view and to
amother command/action in another editor?
This is how I tried but no success:
application has scheme and context e.g.
myScheme
myContext
M1+R is bound to command - command1 and available in most of views and
works fine.
Now one editor has action say editorAction1 and I want to bind M1+R to
that action when user is working on that editor.
In plugin.xml
org.eclipse.ui.contexts
subContext - parent - myContext
org.eclipse.ui.commands
command - id set to ActionDefinitionId of editorAction1 say
editorAction1
org.eclipse.ui.bindings
commandId="editorAction1"
contextId="subContext"
schemeId="myScheme"
sequence="M1+R"
I put code to activate this context in focus gain of editor and
deactivate in focus lost i.e.
contextActivation = ((IContextService)
getSite().getService(IContextService.class))
.activateContext("subContext");
((IContextService)
getSite().getService(IContextService.class)).deactivateConte xt(contextActivation);
May be I am doing something wrong or missing something, any suggestions?
Thanks.

You're close.

you need to define your command and then bind that to the keybinding in
your context (actionDefinitionIDs aren't really relevant) Is it that
you want a completely different command to be active in your editor (say
end-of-line) than active everywhere else (say copy-to-clipboard)?

This is fine. As long as you get your activation from your site, you
can do this once in createPartControl(*) and you don't need the
deactivateContext(*) anywhere (you get it for free).
What you have so far has created the keybinding, context, command, and
tied them all together.
Now you need to add a handler for your command. If you have an action
in your editor, you can do it directly using:
IHandlerService hs
= (IHandlerService)getSite().getService(IHandlerService.class) ;
hs.activateHandler("editorAction1",
new ActionHandler(yourEditorAction));
Use org.eclipse.jface.commands.ActionHandler
Later,
