Is there a default keybinding or a way to configure a keybinding for the "focus view" action that is available on package/project explorer views?
I would use the mylyn context view focusing a lot more if there were an easier way for toggling focus on/off than having to reach to click the view action (I avoid plugging in my mouse to my laptop, if I can help it
If this is unavailable out of the box, I can try to contribute it.
There is no keybinding but this seems like a good idea. Feel free to open a bug at https://bugs.eclipse.org/bugs and push a review to Gerrit. Keybindings can be configured for commands in Preferences > General > Keys so what you would probably need to do is provide a Command that calls the focus action. The tricky thing is that there's a different focus action for each view, and it would be nice to have one command that calls the focus action for the currently active view, rather than having a separate command for each view, but you would need to find a way to get the focus action (subclass of AbstractFocusViewAction) for a view.
