Does what it says on the box, kudos to the author.

very useful.
i like that it does not automatically inject until icon is pressed.
users should note, after checking spelling, one should refresh the page to remove editable mode. (e.g. github tabs cannot be clicked until such)

thank you so much - This allowed me to use Outlook & Gmail properly! However, I'd like to use the 'Context' menu button on the keyboard to activate this if possible.
